MOD 2 found at https://www.thingiverse.com/thing:4275834 Modified Covid-19 Facemask. Standard mask revised to eliminate supports. I will be updating this model soon to better match extrusion widths, preventing small gaps and minimizing retracted fills. A standard 80mm hole punch pattern is used for compatibility with A4 0.2-0.4mm thick acetate sheets. Modelled with no overhangs greater than 45 degrees for added stability. Two STL files are included: one optimized for PETG, the other for PLA. The only difference between them lies in the marking on the inside of the headband.
