Covid FaceMask

This mask uses a user-supplied filter that's easily swapped out. Any material cut into a 38mm / 1.5'' circle can be used as the new filter. Simply place it inside the mask and secure it with the Filter Cover. The CPR mask valve, which is standard issue (https://www.amazon.com/gp/product/B084BVQLBP/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1), directs exhaled breath away from the filter, greatly extending its lifespan. Any 10mm / 3/8'' strap will work just fine. All donations go directly towards purchasing filters and filament for this printer, which runs non-stop. Every mask is given away to healthcare heroes free of charge - no one pays a dime!
