During these hard times because of the corona virus, and with our doctors/nurses suffering plummeting PPE supplies i created this mask to help save precious supplies. These masks can potentially double(if not triple) those supplies. Simply cut 2" discs out of the N95 mask, and insert the discs into the cartridge & cartridge cover. An important detail is to print the mask part in flexible material.
No supports needed and the mask can be scaled proportionally.
