ISO838 Based Face Shield Checker

Check that your 3D printed
Shield is correctly sized

1. Print this sheet at 100% scale.

2. Cut along red dotted line

3. Fold 3 times along
dotted line to get ~0.3mm
thickness. This is similar
to the 125 to 175 micron
thickness of the shield that
https://protectourfrontline.org/
is using. This is between
0.25 to 0.35mm thick.
Paper is typically 0.1mm

4. Fold edge inward to hold
the folds together

5. Punch using a standard
hole punch (6mm dia hole).

6. Test your print
mount point by aligning
the strip to each mount
point.
Should be tight against the
frame so it creates
a seal.
Last hole should be hard to
attach as it should snap on.
