Headphone cord shortener

I wanted to build something to shorten headphone cords. I like to have the appropriate amount of cord; too much just gets tangled up in things.

Also, liking to have para-metrically adjustable things, I made this in OpenSCAD so I could tweak it from time to time.

The same design should suffice for shortening just about any cord...USB...Wall Wart...you name it. Just fix the size of the "eyes" on the end.

Enjoy.
