People that wear magnification loupes cannot use standard 3D printed face shields because there is not enough room between the head and the face shield. Some designs extend the gap (see the well designed https://www.thingiverse.com/thing:4264732). In the case of Optivisor, why not build off of the comfortable head strap and eliminate wearing two things?
This version is designed for the Optivisor line of magnification loops (made by Donegan Optical Company, Inc.) and sits on top of the visor.
It takes advantage of the comfortable head strap of the existing visor.
The 3 hole punch spacing uses UCSF's proven design:

How to make:
1. Print the frame
2. Affix the frame to the top of the Optivisor (double-sided tape, super glue or velcro)
3. The clear part is a clear binder cover, punch it with a standard US 3 hole punch
4. The 3 holes align with the pegs on the printed frame
These clear binder covers work well. These are *not* affiliate links.

Do not use "transparency sheets," they will be too thin and not clear enough.
STEP file is included.
