This is just a simple headphone hanger I threw together on Fusion 360 because the rest of the hanging stands on Thingiverse seem too small for my needs.

This stand is intended to be used with 2 pairs of large picture hanging strips, which will hold perhaps any sized headphones off the side of an applicable surface without screws. These strips, or the Command brand at least, are incredibly strong. It was a struggle to remove it from my desk and put it back for the picture.
