Respirator

READ BEFORE USE!!!

Hi there. I have created this mask for those, who have no commercial respirator but have an oportunity to create it. ALL USES ARE AT YOUR OWN RISK! This mask is not tested and it highly depends how well you make it.

Mask part is in two sizes - M and L - M is for average people. Print it with flexfill 98A or another flexible material. I have printed it on flat side with supports on bed only, overhang 30°, two perimeters, five bottom and top layers and 40%infill. After printing finish it well with sharp knife, so the treads and face rim is clear with no warps or overhanging material. Now this is important: TEST YOUR MASK. Put it on your face and cover tightly all inlet holes. Now take deep breath. If you can get any air, something is wrong. You can add sealing tape on rim and increase sealing of mask, but test it again and again and even while you wear it.

Outlet membrane is also printed with flexfill. Tighten it with M3 bolt and nut or similar. I highly reco
