GM Dash Cubby mounted 7mm ball mount

I wanted a simple and easy way to hold and charge my phone in my truck. A Magsafe style charger seemed like a good idea and I have this stupid cubby hole in my dash that is pretty much worthless for holding anything but it has two holes in the bottom of it where the old rubber piece was attached. This 7mm ball mount bolts into those holes and allows me to attach my Magsafe style charger. This is specifically for a 2011 GMC Sierra 2500hd but should fit any GMT900 (2007-2013) that has that stupid little cubby hole in the dash.

I've included the .f3d files from Fusion 360 so you can change the part to suit your needs. 

Prototype was printed in ABS and would be fine for most needs. The final was printed in PPA (nylon) for the extreme heat in the southern U.S. If you have a very mild climate you could possible use PETG but only for very mild conditions.
