Sunglasses Clip

Clip this to your car visor and it will hold your sunglasses.

After the one I use broke, I decided to make my own improved version.

One thing to note is that this item requires secondary materials and assembly, including some 14-gage spring-steel wire (1095 or the equivalent) for the visor-holder wire, a short length of 12-gage wire for the hinge, and some neoprene rubber glued in to hold the sunglasses in the center.

All parts have been modeled separately to facilitate building and dimensional guidance.

I assume one day that 3D printers will be able to print foamed-rubber, and various metals, and then something like this would a one-shot production, but for now it's an assembly.
