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


This is a design to allow for high throughput small scale production of protective face shields for healthcare workers and others exposed hazardous materials. Fits comfortably and secure on any head size. US/EU style hole punch can be used for adding holes to the transparent sheet.

I modified and simplified the brackets for easier assembly and to allow vertical stacking. The brackets can easily be separated with a flat head screwdriver.
X2,X4,X8 vertical stacked model added, intended for 0.3mm layer thickness and 0.6mm extrusion width(0.4mm nozzle).

I decided to use zip ties as the main component and designed some simple brackets to hold the transparent sheet.

This reduces print time to only about 15 minutes/set and enables a stacked plate of parts. Basically 1 printer can produce 20-50 full visors/day given you have enough zip ties and transparent sheets.
Suggest printing in PLA or PETG. Zip ties are 4.8mm X 360mm.

The design should fit any head size and has a fairly comfortable and secure fit.
Possibilities for sterilization not investigated so far.

NOTE, the design is a WORK IN PROGRESS and has very limited real world testing!!!

I designed this for a Swedish hole punch with a 2 hole footprint, and it turns out this is a purely Swedish thing and the rest of the world uses "single hole" punches. I added a universal bracket that should fit any 6mm diameter hole enabling any punched sheets.

Materials and methods

- transparent A4/Letter sheet
- Swedish Hole Punch, (https://en.wikipedia.org/wiki/Hole_punch -> "Sweden") or other means for punching 6 mm holes*
- 2 pcs zip tie, 4.8mm width and approx 350mm length
- PLA or PETG filament suggested

1. Print 4 pcs of the brackets and 1 pcs of the lock
2. Punch 4 sets of holes at the top of the A4 sheet, each set with two 6mm holes 21mm apart.*
3. Insert both zip ties in one bracket.
4. On one zip tie add 2 more brackets and push in the zip tie tip in the short end hole on the lock.
5. On the other zip tie add one bracket. Note, the brackets identical and unidirectional.
6. click in the A4 sheet.
7. Insert the other zip tie into the lock, size and fit can be adjusted freely.

Assembly video:

The brackets should glide freely along the zip tie, and a light tug on the ends of the sheet might be needed after putting it on.

* There is a universal bracket "BracketUni" for one hole that should work with 6mm diameter single hole punches. 4 holes at arbitrary positions needed.
