A small holder for 3,5mm audio extention cable, screwable to the front of a desk. For use with 18mm boards, but thicker will work too.
I used the very cheap Action extention cable, but my guess is that any similar cable will fit. You might need to cut a little bit of the flexible part to have it fit nicely.
Print it on the large flat area, and use support.

Also: check my USB version of this holder. https://www.prusaprinters.org/prints/63159-desk-usb-holder
