This is a small cable clip that can hold a standard 3.5 mm auxiliary cable, and help keep it tidy. It can be placed on a desk or can hang from the audio device depending on which end you loop twice through it.

To use it, snap the cable through the single cable hole, close to where you want it to be. And the snap a loop of cable on the other side, you can then adjust it by using this loop. The “excess” loop can be tidied up with an additional clip if desired.

I printed in PETG for a bit of flexibility, but it should also work fine in PLA, as the clip isn't under stress once the cable is in place.
