Headphone wire holder

I really like the headphone stand design from Makerbot (https://www.thingiverse.com/thing:2050885). I have several of these printed on my desk.
But I have always been missing some cable organizer in the original design. Having more than one inevitably brings mess in cables - unless you go wireless. Thus I have designed 2 small pieces (the green ones in the picture) which can be glued to the stand with just a drop of some superglue and enables to wind up the cable. The design follows the original design language not to disturb too much visually.
