Respirator/face mask

thingiverse

This is a 3-piece face mask, expertly crafted by Custom3DUSA.com. Feel free to print this design and sell it for any price you choose - they're made from flexible material that fits most people's faces, so one size works well for everyone. To assemble the mask, simply print it flat, then use a soldering iron to connect the chin piece to the rest of the mask. I find that using elastics and a paperclip helps keep the mask securely in place on my face. When printing the "vent cap," be sure to set the diameter at 36.5mm on both the X and Y axes - if you don't, they won't fit properly into their holes. I've been using cotton pads as filters in these masks, which work well for keeping me safe.
