I needed a discrete-ish way to hang my wired ear-pod style headphones under my desk at work. I wanted to mess about with the thread function in Fusion 360, so I cobbled this together. 

Designed to fit around a 1 ½" square desk leg, the thumb screw tightens against the leg and holds the bracket up, and the peg protrudes to hold your item. Definitely not a high-weight solution.

Printed in PLA with supports for the threaded hole and the peg.
