Visor frame and mask shield

These are not my design, I'm just posting them here for ease of sharing.

The N95 shield is a cover that goes over an N95 mask to give it some protection from soiling and hopefully extend it's usefulness. Full details can be found at https://www.facebook.com/collectiveshield/

The visor frame uses a standard 8.5x11 (inches) transparency sheet, with holes from a standard 3-hole punch. Full details can be found at https://www.youmagine.com/designs/protective-visor-by-3dverkstan/
