Here is a pair of sunglasses that prints quickly and is completely customizable.

Build Guide:

Print one of each piece, then insert a threaded insert into each opening on the Frame piece. Next, place the left glasses leg on the left side, and tighten with an M3x8 inserted from the top. Next, repeat for the right side. Finally, glue the Shades to the front of the Frame. Congrats on your new sunglasses!!! 😎😎😎

Print tips:

3 walls

20% infill

4 top/bottom

Shades print guide:

For the Shades model, print it with no top or bottom layers, and at least four walls. I used 50% honeycomb infill, but Gyroid also looks great.
