What do we have here? Well it looks like a simple solution to a common problem using only stuff you've probably already got collecting dust in a closet somewhere. We'll file this one under "Why didn't we think of this sooner?"
This easy-to-source and easy-to-craft solution comes courtesy of ansanma at Instructables.
Grab an old spiral bound notebook (plastic coils are best, but wire should still work) and make a cut in the spiral some length down the notebook. The it's as easy as twisting out the coil and twisting it back onto a cluster of cables. Brilliant!
If you're a visual learner, check out the DIY YouTube video above and don't forget: If you're only cutting a small bit like in the video, you can still use the notebook just fine!
