This is an elastic holder for “horizontal” surgical masks and “vertical” N95 style masks. This style only takes 12-13 minutes to print individually. I designed these after researching multiple other kinds of elastic tiebacks/ear-savers. They can be used for straps that go around your ears(medical), or around the back of your head(N95), based on the orientation of the holder.
V1 has 2 flexible spots so you can bend it gently to match the curvature of your head.
V2 has 4 flexible spots to even further help match the curvature.
