Sunglasses Hanger Ring

I tried a few of the modular trees on thingiverse, and none of them really suited my needs. On the side of some cheap plastic Adirondack chairs, was a flip out cup/phone/keys/sunglass holder. It works really well. So I took the rough dimensions from the sunglasses component, and walah...

Designed to be 4 walls thick, with a .4 nozzle. Shouldn't matter if you use infill or not.

A couple little dabs of hot glue, and they were done...
