USE AT YOUR OWN RISK. NOT APPROVED BY ANY OFFICIAL ORGANIZATION. Big thanks to Walter Renne at the Medical University of South Carolina (MUSC) for sharing the original file and granting permission to post this. This mask is designed to work seamlessly with the filter system I previously posted, which is compatible with the S.A.F.E. system https://web.musc.edu/innovation/covid-19-innovation/safe-cartridge-system-and-masks. One major advantage of this design is that it can be printed without any support material, making it much easier to use. I'm working on releasing both small and large sizes soon, as well as other style filter attachments. For printing, I recommend using PLA with a 15% infill setting (gyroid). To assemble the mask, follow the instructions in the above link. This involves gluing on a seal and adding bungee cords (flat types are best, but small-diameter round ones work too).
