Elastic Cutting guide for COVID adult Masks

thingiverse

This is a guide for cutting a lot of 7" elastics for making medical masks. Just tape down the end in the middle and wrap the elastic around the guide taut, but not stretched. You can use the center divot to run a rotary cutter or slide a scissor that's long enough to make a single cut (to avoid shifting the elastic). I just printed on my Prusa mk2.5. Took an hour to print at .35mm fast print. Hope it's helpful.
