Square Tube Desk Frame Clip-on Headphone Holder

My desk is built using Square Tubing for the desk frame. I wanted something that would click into place around the square tubing and wouldn't let go. This was my third iteration of this design and I think this is the winning result for me. The upper loop is for holding the cable, it's an extra long usb charging cable and I wanted it out of the way, and off the floor.
