USB cable organizer

We recently went on a trip to Europe. My wife doesn't recognize the different USB cable types for charging the different devices we have (A, C, lightning) plus they would get tangled. I decided to make a way to keep them separate with a holder that could be color coordinated for easy identification and allow for easy expansion so just as much cord as you needed could be threaded out. I have made two, one for 1 m cords and one for 2 m cords. Simply wrap the cords around as shown and unwind as needed. 1 m shown.
