Description

I would like to thank our fantastic team at 3DVerkstan who all have contributed massively!

Since the medical community currently (2020-03-20) has a urgent need for protective visors and other PPE for our heroes that spends their days battling COVID-19, myself and my co-workers at 3DVerkstan have spent a lot of time during the past few days designing a printable visor.

This in a WORK IN PROGRESS, and might get multiple revisions during the coming days/weeks, but this first released version is the first one on its way to be tried out by a local hospital.

The plastic shield can be made out of any semi-stiff plastic sheet between 0.1 and 1mm, including overhead film, cover sheets for binding machines etc, as long as it is available in a suitable format.

There currently are 3 different versions. One for SWEDEN, one for EUROPE and one for NORTH AMERICA.
For information about the different versions:
https://3dverkstan.se/protective-visor/protective-visor-versions/

If you need it to sit tighter on your head or if you are leaning over patients a lot and worry about it falling off, a simple rubber band can be put over the two hooks in the back.

For help with print settings:
https://3dverkstan.se/protective-visor/protective-visor-print-guide/

You need approx a 210x210mm build area to print two at a time, and about 160x190mm if you are OK with only doing one at a time.

The 3MF file shows how you can put 3 of these on a single Ultimaker S5 print bed and print them in 21 minutes per piece with a 0.8 mm nozzle.

Materials and methods

A4 sheet of transparent plastic (~0.2mm PET recommended)
Hole punch
3D Printer
A rigid filament
A rubber band (if desired)

Using Raise3D with 0.8 nozzle. Fitting 3 pcs on buildplate and it takes 64min for the whole 3 pcs print.

I have had good luck with using my UM3 with a .8mm nozzle 1 for the PLA and a .4mm nozzle 2 with breakaway support material. I use a .3mm layer height and the frames separate very cleanly. You have to use the dual extrusion files and I modified them to just print 10 frames and 9 support layers. Prints take about 7.5 hours.

Our FIRST Tech Challenge robotics team generated a resin-cast mold approach based on this using the North American frame: https://www.thingiverse.com/thing:4252623

You 3d print a "mold mold", mix silicone, put it in the "mold mold", now you have a silicone mold. Then you mix resin and pour it into the mold. Wait 15 minutes, repeat. A warm oven is needed for resin curing. This enables folks who DON'T have a 3d printer to make face shield frames.

@Alexander Kjeldaas if you follow the directions on http://faceshield.nu, it will guide you how to make Cura slice like that, similar setting should be possible for PrusaSlicer as well.

@Dizzy did you find gcodes for printing two in less than an hour on MK3S?

Adb23e070376bc90962b90eec7b8a8ca?default=blank&size=40Alexander Kjeldaas commented ago

Which slicer will do the layout so that there are long strokes along the edges? Prusa Slicer will fill everything with a constant direction, and I guess that will cause a lot more accelleration and slower prints? Who can share gcodes for a good slice for this?

I tried stacking with 0.2mm spacing using LuBan, but that doesn't give proper separation between the items. Also when printing a single item, I don't think the bottom layer is think enough.

Maybe someone more experienced can give some guidance on how to make the bottom layer thicker, and what spacing is best in LuBan? This is one of my first prints.

Otherwise this prints great on a MK3S using PETG.

The North American 17 piece support stack isn't correct, it is the same as the visor stack. Can someone rue-load just that stl file?

I understand that Prusa Slicer needs some vertical bars going through the stacked structure in order to not complain about errors. It won't slice anything hanging in the air. Would it be possible to add this to the (Swedish) models?

Can i close the loop at the end somehow? every medical worker whcich tried this and has long hair was tangled in this face shield and it was hard to remove from face because the hair was behind the loop hook

Hey, i have two simple questions. Can i use this file VisorframeEUROPEISO838v4-1mm_front with my ender - 3 (no dual extrusion) ? Should i print the stacked version with supports? Will i have any problem with the gap between each visor frame? Really thank you for the design.. I am trying to print non stop for my local hospital !

Everyone requesting stacked versions for single extrusion: LuBan (free software for smaller models) is now including a stacking tool where you can customize separation etc and easily generate your own stacks from the STL files. I recommend that you use the solid brow versions for stacking.

@Yves Lenhard (YL): Use 0.4 AA and Ultimaker Breakaway as a Support material. For the model you can use a 0.8mm AA.

Turn off support altogheter (we're using a custom model as support)

Choose a visor stack file and open it in Cura.

Open the corresponding support stack file.

Right click -> Merge.

Select the support (Ctrl+click) and choose that stack to print with extruder 2.

Turn off prime tower.

First off, thank you for sharing this file - we have been printing it for several days and it has been a huge help to local healthcare workers. I have been printing the 17 high file on my Dimension 1200es printer, but even though it is a very simple file, there seems to be an excess of support material around it. I have seen the same file printed on social media where the support material only seems to be between the actual models. Does anyone have any thought on if this is an issue that can be fixed?

Thanks!

I printed 3 EU versions on a Ultimaker 3 with a 0.4mm nozzle (I think, printer is not mine).

They are usable but not really solid.

Lines are almost coming loose, not really, but it could be better.

I'm pretty new to 3D printing, could anyone tell me what settings to change to solve this for future prints ?

How to print stacked stl with Dual Extruder? Use 0.4 nozzle for supports? Support material? Support distance to parts?

Can you share your stacked settings?

Hello Erik! Love the design and I'm gearing up to print these myself. I was wondering if you could release an updated version that is stackable? It would add tremendous efficiency to an already amazing design. I think that would be a huge help to home-printers everywhere trying to do their part. Thanks again for your incredible work and I hope to see a stackable design soon!

@lilyrmarie Just open Cura, go to preferences in the top menu and click on "Configure Cura". In the window that comes up, uncheck the box "Ensure models are kept apart" and you will be able to put them as you please.

5201122c1ae7e963dd85712ede3c1b54?default=blank&size=40lilyrmarie commented ago

Would someone be able to share a file of the North American 6 hole punch (the one that is solid in the front) where there are 2 shields on the print bed? It looks like there is enough space to print 2 if you put the "ear piece" part of one almost inside the other. I am using Lulzbot Cura software and am pretty much still a novice so when I tried to put 2 on the build plate and orientate them in that way, it wouldn't let me.

Thanks for any assistance you could provide.

Hej friends,

Är det någon som har en prusakompatibel fil, som tar 2 på under en timme, för 0,4 nozzle? Jag hittade en som heter prusaverkstan0.35mmPLAMK2S55m. MEN den har ju plupparna för hålen på fel ställen. Någon som vet?

@zlatko: Generellt avråder jag från flerdelade modeller eftersom du dels får ett monteringssteg och dels får håligheter som blir svåra att desinficera. Jag har ärligt sagt inte sett modellen du refererar till från Garret Lord, så jag har svårt att avgöra.

Sen skulle det säkert gå att optimera modellen ännu bättre för pulverbäddstekniker, fokus för mig har varit att optimera för FDM.

@Christophe C: I have not had very good results with single extrusion stacking, and this is why you are not finding a official single extrusion stacked model amongst my files above. It can absolutely be done, but it requires careful tuning of both printer, file and settings.

And i am doing as best as i can to keep up with all the comments, emails and requests, i spend quite a few hours per day with this right now. :-)

OK, tack Erik. Nästa fråga, jag tänker köra en pack med med visirer i vår lasersintringsmaskin (EOS Formiga P110) och är mellan valet och kvalet om jag ska packa med modulära modelen från Garret Lord och få 105 visirer per körning eller din modell och köra bara 60 ? Några förslag/tips ?

Bra initiativ btw :)

Any advise on how to print stacked and still have easy separation ? (single extruder)

@Jason Cheng

The stacked versions are made for dual extrusion printers and you need to combine the support and the visor stacks to get a full stack to print. I have no experience myself with dual extrusion in prusa slicer myself, so i have a hard time knowing a solution to your problem.

Mini 10268654 10203228803295890 5056406288362677185 nErik Cederberg commented ago

@Jason Cheng: the difference is that the thin part in the brow has its thickness increased to 1mm, it is if you have a hard time getting that part solid.

Any advice on how to get PrusaSlicer to slice the stacked versions? I'm getting:

Empty layers detected, the output would not be printable.

Object name: VisorFrameNORTHAMERICAletter6-holev5-solidfront-supportstack17pcs95mm.stl

Print z: 5.900000

This is usually caused by negligibly small extrusions or by a faulty model. Try to repair the model or change its orientation on the bed.

I'm trying to help a local non profit print these, but can not get the stacked versions STLs to work.

Thanks!

Thanks for all you are doing! I have started printing the NA 6 hole version. I used some of the existing dxf files and imported them into Cricut Design Space. I have a Cricut cutting machine, and I wanted to be able to use it to cut out the shield portion. For anyone that wants to use it, you can find it here.

https://design.cricut.com/landing/project-detail/5e8aa11ade49110b747b73dd

I use the transparency setting on the Cricut and it cuts it out of an 8.5x11 piece perfectly. I resized the holes from the original files just a bit smaller, so they are very secure on the frame.

Really good so far! Thanks for all your work Erik and Team. I started with North America 6 hole and then to 3 holes. I went back to 6 holes after some feedback and my own impressions on how the shield fits and won't shift side to side when wearing it. My daughter works in a care facility and they are not on a list as of yet to get income masks and Sheilds, so this have been tremendous. I commend the whole 3d community for pulling together on this.

It makes sense that the edges be rounded to avoid friction to the face. Many images of health care workers with contact abrasions are popping up all over. I could modify the file if others feel it would be beneficial. Your thoughts?

European ISO839 holes are to be modified

when punching with A6, the holes on sides are too much in coincidence with center of the plot hence the holding of the film is not so good.

please move plots a little towards the end of the branch (like 2-3mm) to ensure better holding. Ceter plots are OK

plots should be a little bigger also

Hi all,

I haven't see anything posted for a smaller, modular version, for those with micro printers. So I quickly put together a design that works with a printer as small as 4"x4" (100mmx100mm).

Anyone know of a particular NHS trust or hospital in the UK that is happy to receive/use THIS VERSION? Where can we send them to?

The Prusa version takes forever to print, but they seem more organised with the 3DCrowdUK website https://www.3dcrowd.uk/

I'm happy to print these, but not if I don't know who to send them to :-)

@Christophe C: I am working on a rework that will extend the front about 15mm in front or so, but just elongating it 30mm will not be a workable option, this would limit the number of printers that could use the design by a lot, since it would be over 210mm long. It is already close to the maximum possible length to be able to fit two nested visors on the buildplate of many popular printers like Ultimaker 2/3, Prusa MK2/3, Ender-3 etc.

Hei,

Is there a version where the face shield is a bit further away from the face.

Depending on the shape of the face, this one can be too close, touch the nose and fog up quite quickly. Putting the transparent sheet 3cm further in front would help a lot and probably be a lot more confortable. (probably the 2 branches going on eather side of the head will need to be extended equaly).

@RabidScallion: Thanks, it is much appreciated!

@johanna jehring: email me at faceshield@3dverkstan.se about it.

@3D_Cupcake: it would need some modification to make it work well on top of the chamfer. Also, single extrusion stacking does have quite a few problems with it. Single extrusion stacking is very sensitive to settings and often leave rough surfaces that are sub-optimal and hard to clean.

Thanks for this great file!

I am currently printing these in the UK, using my schools Dremel 3D45. One person below had a question about fitting these to the smaller print bed. Here are the scale settings that I used to get it to fit perfectly with a standard 4 hole punch:

Scale:

X - 102.42% (Length needed increasing to make up for width reduction)

Y - 98.33% (Width needed reducing)

Z - 100% (Height)

I hope this helps and thank you again!

The Open Cap version at retrolabs does compromise the safety of the PPE, and this is NOT recommended. This kind of change shows a lack of understanding of why it exists.

For stacked versions, I found this page where stacked versions are available for North America and Europe versions:

https://retrolabs.com/3d-prints/3d-printed-face-shield-with-10-mil-pvc

There are STL for stacks of 3, 5, 10 and 30 I think.

There is a variant for "open cap" (no fill in the cap) and "closed cap". I've tested the stack for "open cap" (which is faster to print) and everything was fine, pieces can be splitted easily.

Hei ! getting some inspiration from prusaprinter (https://www.prusaprinters.org/prints/27267), it would be really good to have stacked prints and be able to leave the printer running for 5 or 10 hours (overnight for example). I guess reducing top and bottom surface could help with detaching the visors and leave a decently smooth surface.

Limiting factor would be print time (no more than an overnight print) and filament quantity (usual spools are 750g or 1kg).

Please reply if you like the idea.

Hello to anybody printing the North American version of this frame. I've created a small piece that can clip onto the forehead brace of the frame. It can either spread out the pressure, or have a 4" piece of 1/2" (12mm) foam tape attached to it. Takes under 5min to print at 0.3 layers with 0.6 nozzle and 0.8 line width. I've also created a template for a half sheet (4.25x11) transparency to use as a top cover. These are the two main concerns I see people voice about this design. Here are some solutions:

A standard US hole puncher makes holes that are too small, so a version with smaller pegs would help. I used a 5W laser engraver to make the shields. I found that using a line of electrical tape on the acetate allows the laser's energy to focus on the work area for a clean cut. Cut at 50% power (2.5W), 200mm/min, 1 pass. It also serves to reinforce the holes.

@Icmyip any luck with the 10 stack? A group of friends and business partners are going to be purchasing 10 or more printers to print these or a similar face shield design. If they can be stacked then we will purchase a different printer (CR10S Pro). If they can't we will go with the largest bed we can (CR10 S5). We would much rather have the automatic bed leveling if we are managing many printers... I'd prefer to run each printer with (2) 10 stacks on the bed. Software looks like 6-7 hours with the file you posted. Interested in which direction to go before we spend all of our money on a particular printer. Planning on printing with PLA. Thank You

The Prusa stacked visors come out just fine. Maybe someone can look at how they stacked them. I printed their four stack - which is two and two. Can't believe how much longer and how much more filament that one takes.

@redheadmaker: The stacked file is specifically intended for Stratasys industrial printers that print ABS with soluble support materials. On most single material printers stacking does not produce good results.

@Andrew Normore Thanks so much for the guidance. Took my single print from 1.25 hrs down to 17 minutes. Also, Andrew is right, follow Erik's notes on printer settings. Using a 1.0 mm nozzle dramatic changed my print time and suffered very little in quality. Here is a run down on some basic settings in Cura that I've been using on my Ender 3 Pro 220x220 (no mods)

Cura defaults for the most part with the following changes

- No support

- 1.0mm nozzle

- 0.6 layer height

- 2.4 Wall thickness (2 lines)

- Concentric Top/Bottom pattern (thanks Andrew)

- Fill gaps everywhere (nominal time difference and fills holes)

- No infill

- 210 Default printing temp (gets worse with lower temps for me)

- Enable retraction with 8mm distance

- 80mm/s print speed / 40mm/s wall speed / 30mm/s initial

- Combing mode = All (helps with not having to clean up and no big change in time <1 min)

In the middle of trying out @Icmyip stack print. I'll update to see how I do but my white filement needs a higher temp for some reason.

PETG is extremely sticky so I'm not surprised. I imagine it would work much

better with PLA. I'm going to try stacking a different model in a similar

way tonight.

Stacking didn't work with the PTEG filament I'm using at all, even using the model with a solid splash guard from our volunteer.

@redheadmaker make sure it works ok by printing the first 2 units in the stack then stopping the print before you leave it on over night to validate that it works with your printer and filament. would be a shame to waste a 1/4 of a roll of filament overnight.

Yes, I could slice this latest one. I will start it up before I go to bed. Thanks! I just gave 20 of these away to a firefighter friend of mine that said his house has 26 firefighters and only 6 face shields.

@icmyip

that version slices fine with no supports in prusaslicer 2.2.0.

I'm concerned about the bridging of the splash guard section however. The design our volunteer made turned that in to a solid section, only adds 2 grams of materials per frame, and still splits apart perfectly fine.

Can you try this file?

I modeled the separation based on the Prusa RC3 stacked file you linked. Shouldn't need to enable supports for this. I did have to add some supporting cylinders in the forehead part of the model to support the next print. May end up actually being faster to make the entire forehead piece solid and hollow it out when slicing.

That is ugly if I turn on supports. They aren't only in between. Prusa slicer supports are kind of a pain.

I was refering to the prusa RC3 stacked file. https://www.prusaprinters.org/prints/27267

PrusaSlicer will not slice the Stratasys stack that's on here without supports either.

I've re-created the Euro A4 DXF file so it now works well with the prints I've created. The screen still stays attached if the visor is used by someone with a larger than average head, or when someone with a small head uses it. Visor needs to be flexed open for the screen to be attached.

Tested using 0.1mm OHP film,.

Which Prusa stack are you referring to? The only stack I found in the documents section was for the Stratasys.

Thank you Icmyip, I assumed you had it designed like the prusa stack with supports already built in.

will try once my current print is done. Slices fine with supports.

F7dde25ed46625b0a2720ac55e3b263d?default=blank&size=40lcmyip commented ago

The empty layer is likely because the way the template I followed (Swedish/Stratasys file) connected each model to the others was using a narrow 0.2 mm rod going through all the models. Would be interesting if Slicer/PrusaSlicer has the same error with that file. This is likely unprintable for most printers hence the error with the slicing software finding an empty layer. I assume you would use support material between the layers though? I can redo it using a wider diameter rod if that would help.

To be honest, I'm unlikely to use these stacked models myself in the near future but I don't mind doing the CAD work if needed.

F7dde25ed46625b0a2720ac55e3b263d?default=blank&size=40lcmyip commented ago

Do you have supports enabled? It slices fine using Cura.

C5e675414922a419141f274793b09015?default=blank&size=40Petko Ganachev commented ago

lcmyip's design gives an empty layer error in PrusaSlicer, any way to get around that?

Also, one of our members created this design, same issue however should be easier to print since the splash shield will have some support when printing the next one. it printed very well for the person that posted it. (scale to 10% of original size to print correct dimentions.

My printer is currently occupied by another PPE project so I haven't tested

the stack. I made it based on the Swedish/Stratasys printer version, but

using my chamfered model instead of the original v.3 provided here.

Slicer won't slice the stacked file with 10, here is the error message:

Empty layers detected, the output would not be printable.

Object name: VisorFrameNORTHAMERICALETTER_v3.3-stack10.stl

This is usually caused by negligibly small extrusions or by a faulty model. Try to repair the model or change its orientation on the bed.

I'd LOOOOOVVEEEE to see a stacked version. It would be great to have

someone figure this out. I'm babysitting my printer every 20 minutes to

take one of the bed and get the other one printing. On another note though,

I'd also like to see easy cleanup. Printing one a time makes it nice

because I have little to no cleanup. Hopefully you guys can figure this out

soon. I have one maybe two more printers on the way where I can print three

on the same bed so if they're stacked even better so the bed & nozzle heat

up time wont be a factor.

F7dde25ed46625b0a2720ac55e3b263d?default=blank&size=40lcmyip commented ago

This is great! Our prototyping lab has been printing various designs and seeing what would be most feasible. I like this one due to how fast it is to print and requiring only two parts.

Any chance the CAD file would be available? I notice at least on the North America version that it is chamfered on one side only. If I had the CAD file I could easily chamfer the other, and also help make stacked versions if needed. I can reverse-engineer the file using the STL, but it's unnecessarily complex....

6fd26173aacc0ab71f3e9dd45547330f?default=blank&size=40andy_spoo commented ago

I think those DXF files are wrong.

My second printer/bed isn't large enough to print a whole face guard but I've cut the STL so I can compare the distance between the pins/holes and both printer produce holes/pins that are exactly the same, but neither coincides with the DXF file cut on my laser cutter. The laser is conformed as being calibrated correctly, so my conclusion is the DXF files are incorrect.

I've tried both the Europe ISO and non ISO A4 files, neither are correct.

Erik! I made a small band that snaps onto the forehead rest of the frame. It only adds 5 minutes and 2-3 grams of material per print. It's helpful for people that need to use a rubberband to keep the visor on their head. I've sized it to use 1/2 inch or 12mm high density foam tape.

As far as this comment can be useful to those who have chosen to print the Europe version and the template corresponding to the 4 fixing pins. Using the punch, position the template in question printed for a test and justapose it on the plastic sheet. Once the perforation is made, the plastic sheet is well positioned on the frame.

I've tried the Swedish version with Swedish STL files and Swedish A4 dxf laser file and the holes in the shield aren't ligning up with headband. I've ran wide calibration tests on both my laser and 3D printer and they're calibrated just fine.

Are their original model files rather than STL files available to download so I can check what the accurate distances of the pegs on the model should be so I can work this out??

Thanks,

Hi Erik, awesome design! I don't have a 3D printer big enough to print it, so I made a derived design (with credit to you of course) that can be made on 3D carving machines and published it to Inventables: https://www.inventables.com/projects/covid-19-protective-visor

I made it with a sheet of 1/4" thick MDF and it works beautifully! It carves in 11 minutes.

@Tim: Hi, the closed top is a requirement for many hospitals over here, they will not accept a fully open top since it compromises the protection from drops from above.

A bit further spacing is a possibility we are looking into.

83cac326cb202ccdde2eebdecce3bb21?default=blank&size=40Tim commented ago

Compared to the Prusa design, I like how much faster this prints and how much less material it uses. I think the shield is held more securely too (NA letter design).

However, the closed top really does not ventilate well. The mask fogs easily and I find I am re-breathing warm air. It is also is too close to my nose. The Prusa has much more generous gap.

Is it not possible to space the top farther away and provide some more ventilation?

How smooth should the surfaces be? I printed couple of them above each other with breakaway material as supports. It peeled away pretty neatly and the surfaces seem ok to me yet there is a noticeable difference compared to one layer printing. How do I know if I rather should stick to one layer printing?

@Tombsology Confirmed. This distance between the center holes is what you get if you use a 80mm hole punch set to A6 and punch a A4 sheet from both sides.

See the instructions here:

Mini catTombsology commented ago

I printed off the Visor Frame Europe Iso838 V3 but the front hole centres did not print at 80mm centres, more like 68mm centres. However, the hole centres from either front hole to the side holes are correct at 80mm. I am using a Tronxy-XY2-Pro.

Can anyone else confirm if the front hole centres are not 80mm apart please ?

@Andrew Normore: the click-togheter solution has been discussed, a lot, and there are two problems.

1.) It introduces hard to disinfect cavities. The hospitals we talked to say this is a non-starter for them, they cannot have parts that have joints where they will not be sure that disinfectants will reach.

2.) It drastically increases the tolerance dependency, so makes it much harder to do a well working print, especially with larger nozzles.

Otherwise, i agree.

This is just awesome! Doing my best to spread the word to friends and groups. Too bad I am home sick with influenza-like symptoms (not verified CAVID-19) - so does not meet the demands. :-(

However - looking through all the pages and files - I have not found a single notice on expected or recommended infill-percentage and parameters... Maybe write that under "Materials and methods" since it also effects your printing-time if you use too much!.

Smaller version for smaller printers:

I tried to print the Visor Frame Sweden V10 in an old Makerbot replicator, but print area was a little too small so I copied the idea creating an STL with max dimensions 178x139x5 mm. (The version is not as good as 3D verkstans since I'm a complete newbie at 3D design) Contact me for receiving the version for testing it out

Is there a hole layout for the european version with four holes?

So its easier to try out.

@Dalfandor Thank you. I am not good at editing but can you make that into a svg or dxf? Also if you can make it with round corners. Also if you can make one for VisorframeSWEDEN_v10

As I started to print that and the files included do not work for that one as well. I'm so close to just tossing all these and giving up at this point. Have about 20 :( no hole punch only using a cameo. Really appreciate it!

Suggestion: Make the side pieces separate and click-together once printed. This would allow everyone with smaller printers to get started, and let bigger printers do more per run (overnight jobs).

However none of the laser cut files fit this. Is there plans of creating a laser cut file for this?

I like the idea posted earlier of printing several visors on top of each with supports as break away material. But I assume the design will have to modified to fill the tray area near the forehead. Or could supports be generated in the tray area, and hopefully bridging is sufficient for the bottom tray layer.

Also, what size is the hole for the US letter template? 6mm or 8mm?

@darksider63: a easy way to adjust it is to just dip the temples of the frame in hot water from a tea kettle and adjust to your liking. The fit will depend greatly on your head size and shape, so making a one-size fits all is very hard.

Could you possibly share the SLT that you mentioned that you use:

Visor Frame Sweden - Ultimaker 3's with the 0.8mm core.

(I suppose it does two at a time)

And possibly if you have, the same but for the 0.4 core as well.

Thank you.

@Kim Nilsson: You need approx a 210x210mm build area to print two at a time, and about 160x190mm if you are OK with only doing one at a time.

At 3DVerkstan, we are producing these mostly with a number of Ultimaker 3's with the 0.8mm print core for faster printing: https://3dverkstan.se/ultimaker3/

What are the size requirements? I can't find that written anywhere, and I don't have a 3D-program yet that can tell me. I was just asked to help out picking a fitting 3D-printer to start producing visors here for our municipality in Sweden.

@jymboche The north america frame is to be used with the spacer also provided and a regular 3-hole punch. The template file you looked at is to use a single hole punch to fit a letter sized sheet to the original Swedish version. I might need to clarify that.

Please see more information here: https://3dverkstan.se/protective-visor/protective-visor-versions/

@Jonas Bohlin You could probably just use two plane cuts and cut down the length of the pegs slightly to fit 155mm, try Meshmixer.

Hi @gmorain

The cleaning used here in Sweden is dunking in or wiping with a Isopropyl Alcohol (>70%) based disinfectant, and ABS is compatible a quick wipe or dunk, but not with extended times in the bath.

PLA and PET is both more resistant.

Hi @Arkemist.

If you can make the breakaway layer to come of smoothly and give good finish at both sides, it would absolutely make sense. I have not had time to try this myself yet.

3c5dd6e7c1b341cab433cb63764de20f?default=blank&size=40Arkemist commented ago

Hi Eric,

Wonderful work! Hope it gets approved by the authorities!

Would it make sense to print the visors in several layers on top of each other using breakaway material for support between the layers? This is to be able to leave the printer do its thing for longer and getting more visors in one go.

/F.

Hi Eric, thanks for sharing this, I am currently printing some for doctors around me (western city in France). I see it is currently being tested by a local hospital, do they have issues with other materials (I only have ABS here at home) ? I was wondering about the chemical properties vs medical cleaning process...

Great design! I tried to print this on my Flashforge Inventor, but turns out the prinbed is 155 mm wide. Is there any way to modify, to accomodate a narrower frame/sharper visor curve, or is that pointless?

The screen touches my eyeglasses when mounted (testing with A4 paper). Front might need to be slightly wider, or altered as per Gergely's suggestion.

https://www.hzn.hr/UserDocsImages/pdf/HRN%20EN%20166_2002.pdf

Another tip in case of using this as a last-resort: PET bottle can also be a source of a fairly strong PET sheet! The curvature might not be idea, but thermal treatment could help there.

I still need to get transparent screens, but it's relatively comfortable. The hospital says that the comfort is important and that it the nose bridge is what makes them uncomfortable, this design might actually avoid that problem altogether.
