Spool winder headphone cable

I've been searching for a long time a spool winder for the extension cable of my headphone, i tried 5 and more type of spool, the problem was that are too small for 5 meter aux cable and if i resized it wouldn't fit anymore, there was only a solution:make my own spool winder.

I didn't include many function because i want i simple and easy to print; a good idea was to block the beginning and end of the cable, but it works well anyway.

Work well for 5m aux cable no other test done

i hope this helps.

PS: the knob is resized at 95% for the thread
