Seeing all these open-source anti-viral masks online, I thought to myself, "Self, why don't we get in the game?"
And so we did.
This mask is easy to put together and easy to use. Wishing you the best of luck, please keep safe out there!
1. Print out the main mask part.
If you are smaller or larger than 6ft tall (1.83m), you may need to resize the mask to fit your face. I would recommend using this formula:
Your height/6ft = scaling factor of the mask.
For instance, a person who is 5 ft tall would scale the mask to.83 or 83% of the size given in the attached 3d model.
2. Print out two each of the screw and nut. These can be printed with your default printer settings, I just did like 15% infill.
3. Glue the CPR valves onto the mask, making sure to put them in the right way. You should breathe in through the sides and out through the center valve of the mask. The thick ring around the center of the valve should be inside the mask for the side valves.
4. Glue the screws onto those CPR valves, threads out. Use LOTS of glue, you want an airtight seal.
5. Cut some vacuum bag fabric into a little circle that will fit inside the nut. Put it inside the nut, making sure it fills the entire circle area, and then twist the nut onto the screw.
6. Test the mask to make sure it works. Additionally, you can make the mask more comfortable and more airtight by adding weather stripping to the edge that touches your face.
7. Replace the filters after 8 hours of continuous use.
8. Be safe and wash your hands!
