It's just a simple sunglasses frame that looks very beautiful. I originally wanted to find a free one, but I wasn't lucky enough, so I made this one. It consists of three parts that snap together. No glue or other adhesives are needed. Use double-sided tape to fix it to the wall, or drill some guide holes in the backing frame so that it can be fixed to the wall with screws. The front panel will cover your fixing device.

I've used it beforeUrunAtolyesiModeling on things to save me the time of modeling wave patterns. https://www.thingiverse.com/thing:7190274
