We designed and prototyped this face mask that can be easily made in less than 10 seconds with a laser cutter. We don’t make any claims about material effectiveness or what material these masks should be made from. Mostly we just wanted to get this design ready and available online as a starting point, because we didn’t find another one quite like this yet. Below are links to the SVG and DXF files. The size is small but can easily be increased using the free software Inkspace. We may have the opportunity to post other sizes in the future. There is also a fold-able two-layer mask that could be combined with a more effective filtering material inside the fold to greatly increase protection.
