Rotating Car Charger / Holder for iPhone 4S (modified)

I modified the original model by Berslan to use 8mm x 3mm magnets found at Home Depot. I also changed the bearing to a 16mm x 5mm x 5mm that I had sitting around. My iPhone wasn't very secure without the cable so I added some grooves in the holder on the sides and back corners that I could insert some of my NinjaFlex filament to act as a cushion and grab the phone more.
