Rear strap for Prusa designed Face Shields. Loop the Right Strap to the right side and the Left Strap to the left side knob, and loop each strap into and out of the clip.

Straps should be printed in something flexible, like TPU, and the clip in something rigid, like PLA.

Edit: I shortened the strap by 5mm, so you can fit 10 of them on a Prusa i3 bed. This is v3.
