N95 Upgraded Mask Double Intake

thingiverse

This is a remake of the Nanohack mask from Copper3D, updated from this mask: https://www.thingiverse.com/thing:4233943. I made some improvements to make stronger threading so prints can be done in draft mode. I also added better grip to the cap for easier removal. You need to print two caps and two honeycombs per mask. HOW TO MAKE 1. Print the files with PLA, 20% infill, 0.3mm nozzle, and activate supports - trust me on this one. 2. Heat a skillet filled with water to 60-65C. Place the "bottom fin" of the mask in the water. After a few seconds it will become pliable. 3. Shape the bottom fin so it folds in and the outer flaps fold up, holding the chin. You can shape it around your chin; that temperature won't burn as the PLA doesn't hold or transfer heat well. 4. Then repeat with the sides. Last, shape the nose flaps to your cheeks and face. 5. Use glue or silicone to fill in any gaps from the chin flap and nose flaps. 6. Get some rubber bands or straps to hold it on. 7. Cut some cloth or surgical masks to the shape of the circle air inlet. You need two per side, four in total. Use the honeycomb disc between each filter for support. 8. Make sure to wash or soak with dish soap and water every day of use. Dish soap breaks up the lipids that make up the outer encasing of COVID-19. Don't put it in the dishwasher as the heat will deform the mask.

Update 3/25/2020: There was a glitch in the previous mask where the threading had too small an internal radius. I fixed it with the updated design, so it now fits correctly with the cap.
