Simple DIY mask with flexible filter media options. Three sizes available; small, medium and large. Use string, elastic cord, rubber bands, or other options to secure to head. anchors around the frame are very handy to wrap string around for a snug fit. Mask frame will conform under tension, or can be heated and formed to the face.
Ultimate goal is a low cost, fast printing, simple mask that could be used and discarded.
"Make everything as simple as possible, but not simpler." Einstein
This is a very fast print at 14 minutes for the large sizes. Two larges, three mediums or three smalls can fit on a standard 200mm X 200mm build plate.
ABS and PLA are both acceptable materials to print with.
Note: This mask is not as effective as a N95 HEPA, MERV 16, etc. but this is better than nothing.
