Print this thing, pull a string through the holes on the side, wrap a hanky over the frame, and glue the hanky at the edges of the frame. If done correctly, few seams are visible from the outside, put the glue inside the mask. This will give a simple, reusable face mask. Simply exchange the hanky when needed, at least once a day. It is possible you need to adjust the mask slightly to your needs.

There is no guarantee of any kind on this object. There is no proof that it helps in any way against infections, though I certainly hope so. It is possible that viruses may penetrate the mask. It is hoped that this mask adds to your protection, but you will still need to keep a distance from other humans. The item is not designed for professional use around infected persons.
