How to make the strap

Tools • Pencil • Compass • Fine liner (I used the smallest fineliner I have which is size 0.05) • Geo triangle (To make sure the everything is nicely straight) • Cutting mat/board • Scissors • Ruler (Preferably made of metal to cut nice straight lines with the knife) • Stanley knife (to cut the design out of the plate)

Material PET-G (0,5 mm thick)

Tip: Do not draw directly on the PET-G plate itself. The PET-G remains nicer if you remove the protective film after cutting out the shape by hand. I first drew the shape on a piece of paper and then taped it on the protective foil. But you can also draw it directly on the protective film.

1. Measure the space between the ears

2. Draw these lines with a pencil amd compass

I made my strap 15 cm wide in total, but you can also make it as wide as your own measurements. Leave space 1 cm 2,5 cm

What I find the easiest is to first cut the straight lines with a stanley knife.

And guiding the knife with a metal rular. [YOUR MEASUREMENT - 2 cm]

And than cut out the round parts with a pair of scissors.

Remove the protective film

The strap is now finished and you can test it.

Slide the facemask wires in the splits in the direction the arrows point towards. Thats how you lock the adjustments to wear the facemask correctly according to your personal fit.
