About this 3D model

This is a replacement for the magnetic mount for a Mountek nGroove Snap mount (http://tinyurl.com/pq9sk9t). My wife got a semitransparent case and she didn't like the metal plate being visible. So I designed a cradle type carrier in it's place. I printed the ball socket from ABS as the PLA prints kept cracking at the joint between the cylinder and the plate. The cradle has extra space for a thin case. The Google Nexus 5 case is too thick to fit (a guy at work has one and it would not slide in). The power plug hole is sized for a Monoprice USB A to Micro B cable. Cannot find the URL for the exact plug right now.
