Headphone adapter holder
Tired of losing the adapters coming with your headphones? Then print one of these and zip-tie it to the cable, and you can just put the adapter in the holder when you don't use it.
You will need two small zip-ties, the one i designed it for are 1mm thick, 2.5mm wide and the head is 4.5mm wide. Stick it in from the bottom and the tie head should be possible to fit in the body of the holder
