iPhone 6 case with cutout for Spigen air vent mount plate

This is a remix of hangsta's great iPhone 6 case model with a .6mm deep cutout for the rectangular metal plate to be used with the [Spigen magnetic air vent mount](http://www.amazon.com/Spigen®-Magnetic-Neodymium-Holder-iPhone/dp/B0109JIQ0W). Use the provided protective film over the plate to prevent scratches to the phone.

Added a model for the round plate as well.
