Based on original design: Protective Visor by 3DVerkstan by Erik Cederberg


Thanks to the original designer Erik Cederberg at 3DVerkstan.

This is a two piece design to allow single extruder stacking, using a 45 degree taper down to a line, to make separation possible without any support materials or fine tuned settings. The cover part is separated from the frame so that no bridging is needed.

Separation can be a bit tricky and takes about a minute per piece, but allowing overnight printing will probably make up for that.

Only the Swedish 4 hole version is available at the moment.

Materials and methods

How to separate: Use a sharp and thin breakaway/razor/stanley knife to separate the frames. Use gloves and cut away from your fingers. The knife has a tendency to get stuck but then jump ahead as the layers separate so be careful!
Inspect and cut away leftover pieces on the top and bottom side.

Attach the cover piece (the visor does not work without it) by aligning the snap features and pressing firmly. The flat part of the cover goes on the top side of the frame, hooks on the tapered frame side.

Tested the design using PETG
Use the 3 piece test file to evaluate before committing to the 22 piece stack.
You may nest the two parts, but optimal settings is different so separate printing is recommended.

I have included small mouse ears which is probably sufficient if you have good first layer adhesion.
If you are uncertain do use a brim to ensure a successful print.

Ah that explains it clearly. You show the original design, mine looks a bit different:

I'll try to extend the cover even more to eliminate the gap completely.

Thanks for the feedback!

I've done just over sixty of them so far, on an Ender 3. Regarding the small gap problem, here are some images:

Thanks Craig for commenting!

I see what you mean with small gaps, I suppose my design is not great in that regard due to the clip/hook feature to attach the parts. But I'm not sure exactly where you propose I add the chamfer? If you explain a bit more I will absolutely try to add that.

I assumed they would submerge the whole visor in disinfectant, since the 3d printed part is porous in nature anyway, so there is lots of gaps you cannot reach by wiping with a cloth or something.

If anyone successfully printed this, please let me know, thanks!

One suggestion, hospitals have commented on another design that. I have been involved with that small gaps (such as lettering, etc) can make sterilising the shield more difficult. putting a rounded chamfer in the tiny inside gap between the temple and the forehead brace would probably be a good idea
