Headphone Hanger Under Desk

I wanted a simple and low profile headphone hanger for under my desk and so I over-engineered this. The idea was that the dovetail lets you not use supports and it'll hide the screw. You still need supports to print the hanger part, didn't think that through, but I printed it in the “flat” direction so the layer lines are in the stronger orientation and that didn't need much support.
