https://copper3d.com/hackthepandemic/ The manufacturer of 3D printing materials Copper3D has just put online an open-source STL file of a N95 mask, which can be 3D printed and used against the COVID-19 virus. You can find the instructions on a link provided upthere. There are 2 versions, I printed the original one on Creality Ender 3 PRO. Flow at 160% (maybe a little to much), 220c with PLA Strongman (a little bit durable PLA). After more than an hour managed it in perfect shape and dont need any additional sealing. Juncions first glued with cianocrylat, just to fix them, then sealed them with epoxy. Also made a key for filter cover which is also usable as a dust cover due to it's tight fit. Made also a filter cover with biohazard sign (just to make people more aware from the virus) Update: I aded mask with two filters for easier breathing and filter cover for the right side with left thread
