Micro USB carkit holder

I wanted a charger with my carkit holder, but these are not most of the time not universal and quite expensive when you buy it for your phone model. ( I got the SIII and it was like 55,- Euro)
So I got myself a cheap carkit, and printed out a micro usb holder so I can click in the phone everytime I get in the car so I don't have to look for the cable to plug it in first, then put it in my carkit.
