Prusa RC3 Face Shield TPU Strap v8 - One Size Fits All

This is a one-size-fits-all TPU strap for the Prusa RC3 Face Shield model.

It is 273x30x1.5mm, so it will fit on any 30cm or larger print bed without having to print at an angle. Takes roughly 30 minutes to print with the settings listed below and uses ~6g of material.

Comes off printer 273mm long, stretches to 400+mm.

Connect strap to mask using thicker holes.

Pick the size that fits. Use the stretch of the material to ensure a comfortable but snug fit.

I am unable to break the strap with my arms but if you'd like to make it even stronger, scale up the Z axis in your slicer and print it thicker.

This is removable and reusable; depending on regulations/procedures and whether you have the appropriate cleaning materials/facilities on hand.
