Headphone bracket, one piece, no supports and no screwing

Please share your makes, I'd love to see them :) A headphone bracket to mount to desk or shelf without any drilling or screws needed with a USB charger cable storage mount. I have included the main bracket, a number of spacers and an optional removable mini compartment. My desk is just under 22mm thick and i used the 0.5mm spacer which makes a perfect tight fit. Find the one for yours and use a folded piece of paper if you need the final gap filled to make it as tight as you would like.
