Straps for Montana Mask Respirator

thingiverse

I've been creating Montana Masks for local hospitals and ran out of elastic. So, I came up with an alternative solution using TPU or a similar flexible material. I'm currently utilizing SainSmart TPU, which works well on my Prusa 3D printer. Clips should be made from something rigid, like PLA. You'll need two clips and four straps for each mask, with one strap passing through each loop hole on the mask. Then, run two opposite straps through the clip, into the middle slot, loop over, and out of the outer slot. This allows you to tighten the straps by pulling on the loose ends. To remove the mask, pull the clip away from your head to loosen the straps. Edit: I've created a shorter version called Mask Straps Shorter, which can fit four sets per bed with a Prusa i3 printer (210x250mm print bed). I also increased the size of the hole blocker so it'll fit with the SLO Respirator remix at https://www.slorespirator.org/.
