Surgical Mask Frame
Surgical masks are easy to find but offer limited protection. One of the issues is air going through the gaps to the side of your nose, cheeks and chin. Use this frame to better fit the surgical mask to your face, closing those gaps.
Apart from the basic STL model there are two other variations included. The Full version add slots at the top and bottom so you can pass mask material through if needed. The FullRings version adds some rings so you can add your own straps.
Use the FullRings version to create a makeshift mask from some cloth and a couple of elastic bands.
I tried printing in different materials: PLA, PP, ABS, PETG. They all seem to work well but the PP is too malleable and doesn't fit as tight as the others.
Printing time for the basic model is 9 minutes. Printing at 200% speed cuts that down to 6 minutes on my PRUSA MK3.
