3D Printable N95 Montana Mask by Rob Luft
The montana mask was created by longliveyoursmile.com they released this file they are using to help with the n95 mask shortages. I have printed and tried it out. They fit quite well. You can use dish rags, tshirt material, paper towel or anything you can think of. You can use the n95 paper masks and cut them into about 6 pieces to get more uses out of one mask.
