These come in three sizes. Of course that doesn't help if you don't have a 3D printer, and if your 3D printer is a tiny little Anycubic Photon the whole "prints without supports" is a lie because you need to turn the thing upside down and suspend it in space. My wife sews. She's probably made 40 masks for the birth center.
I’m not really looking for a mask to protect me, it’s impractical to wear those except in high risk areas like airports. I still have a few fuck you Im protecting myself and not you 3m masks for those situations. Looking for more of a face covering to decrease any potential germ dispersal and to signal to my liberal cohort that I respect them enough to wear a mask when I spend time with them. I see it more akin to wearing pants than safety glasses or a helmet in those situations.
