Subscribe Now! Yet another easy printable and usable mask. The shape of this design will cover your chin. Design inspired by an antique TLR. First prototype equip with two extended hooks for strap which looks like the aperture and shuttle dials. Now is a bit too sci-fi. (Updated 17-Apr-2020: Added 3M and Moldex filter cartridge support) Please always check for update before you do the next print.

I get quite a few requests to convert this design for printing in PLA or PETG. Sorry, but I am not going to do that, and this is why: In my experience, PLA and PETG are TOO DANGEROUS to put on your face. If a PLA or PETG mask cracks, especially when printed as a light weight/thin wall, it will cut your face like a knife.
