Mask strap clip
thingiverse
Mask strap clip broke from my Ursuit Frameless mask so I did a quick modeling work and printed a new piece. This should work on other masks too if their strap design is similar. Outer dimensions of the clip are 24.5mm x 12.5mm x 9mm. Use 100% infill. I don't recommend printing this in PLA because it's not UV resistant. I printed mine in PC.
