Plain Shutter Shades with Filament Hinges
thingiverse
I wasn't having any luck with snap together shades so I swapped the hinges from the 2020 glasses. The best of both worlds??? I recommend printing your shades with something stronger than pla. One of the hinges broke while I was forcing the filament through the holes. Also don't do that. Bore out the holes with a 5/64 inch or .2mm drill bit. I was able to save my pair of shades with 3d pen and a drill bit.
