This is cable organizer that I have created to get my micro usb cables get better organized. Thing is developed with OpenSCAD and you can customize is to your needs. Sources are included - enjoy!

This thing is inspired by http://www.thingiverse.com/thing:570074 but I wanted spool that has smoother angles so it would not bend cable too much and made some holes so cable has more space inside and easier to access.

Update: I made body little thicker and increased number of clips, removed useless hole that I wanted use initially for the cable.
