Face Shield - 3 holes

Modification of the Prusa face shield that uses 3 supporting pegs instead of 4, which allows for a creator to use a standard 3-hole punch to easily covert a transparency slide into the shield.

I also added some engraved text to the inside of the frame with a URL so that anyone who comes across one of these in the real world can know where to go to find out more and make their own.

However, because this text adds additional time to the print, I'm also sharing a version of the file with no text, if maximizing output is a priority. Use the file FaceShield_3_holes_no_text.stl for that.

Update 3/26: Please see this video for how to make a simple improvement that will provide additional coverage to the top. https://youtu.be/Ldy9V4J4r6g
