Face Shield Plastic Hole Template

So I like the simplicity (and that it fits on my build bed) of the face shield headband at https://www.thingiverse.com/thing:4264382 but don't have a hole punch, only a drill, so I wanted a guide.

This jig lets me quickly drill 3 holes 70mm apart that fits the face shield referenced.

Then I used https://www.prusaprinters.org/prints/27950-prusa-face-shield-us-version for the bottom brace, and just drilled out one of them to act as a jig.

What to print:

If you have a build bed > 160mm, print:
* Parts A & B - All-in-one (1x)
* Parts C & D - All-in-one (1x)
* Clamp (2x)

If you have a build bed < 160mm, print:
* Parts A & B - Individual (1x)
* Parts C & D - Individual (1x)
* Clamp (2x)

Updates:
- 2020-04-15: Added 1mm more between the holes as some of my masks did not quite fit.
