Very simple sunglasses that I designed to use with those cheap party neon sunglasses lenses on amazon for about $1. Customize them however you want! Let me know what you think!

After printing the parts, you will need to scavenge screws and the lens from the neon party glasses. Or just buy some small screws (sorry, not sure of the size).
Here is what I used:

After printing, I treated it with a cold acetone vapor bath to get that smooth look. Let it sit and harden over night or a day before pressing the lens in.

Have fun printing!
