Designed originally for a 2012 Prius, but will probably work on many car models. This simply snaps onto the louvre of the vent fan, and provides a place to slip a cable through, to keep it out of the way of your center console. Perfect for those gadgets mounted up on top of the dashboard (GPS, radar detector, phone cradle) but which are powered from a socket or port below. Solves this problem without sticking anything to any part of your car; the cable and clip are both easy to remove and replace at any time.
Probably will look best in black, if your car console and cable are both black. I can't recommend it in materials other than plastic since it depends on the slightly springiness and flexibility of plastic.
