Headphone Cord Wrap, now with less happiness
Remixed versions of Swighton's 'Happy Headphone Cord Winder': http://www.thingiverse.com/thing:6999
I liked the idea and also have trouble with too-long headphone cords, I just removed the Smiley Face and put up a version with no interior, and then one with some cross supports. not that i think itll need them, but a little extra support never hurt anyone.
