6800 Respirator Glasses Mount

thingiverse

The spectacle adapter for 3M (style) respirators are a little hard to come by, but as a chemist who occasionally needs them, they're a lot safer than contact lenses. This mount is very similar to the official ones, but can be printed, and thus doesn't involve being annoyed at suppliers. I printed the brackets in PLA, and the frame in TPU. The wires are 1.5mm; I used nitinol since it was to hand, and means they're nearly unbreakable. The frame was designed around the lenses out of an old pair of glasses rather than a standard, so you may need to adapt it to yours.
