This is a simple, low material hook that fits in a usb slot.
My monitor has a usb slot that I do not use so why not utilize it to hang my headphones?

The model only uses .27 cubic inches of material.

This was printed on a production quality Fortus 250mc.
Print settings:
Layer thickness of .007" with the smallest contours and surface rasters

If anyone would print this out on their hobby printer to check fit and thickness I would really appreciate it, as my setup isn't a true reflection of a normal hobbyist.
