About this 3D model

This is an adapter for my old car dock. The dock uses a little slide in lock system for mounting the actual phone holder. I’ve designed this so I can print out a new holder for my new phone and attach this to it to use the same suction cap base mount. I’m not 100% sure but I think this is the official Motorola car mount for the original droid. This seems to be it http://www.amazon.com/Motorola-Generation-Vehicle-Charger-Packaging/dp/B002Y3BYQA/ref=sr_1_4?ie=UTF8&qid=1325698518&sr=8-4 I published the rest of my new car dock separately here http://www.thingiverse.com/thing:15490
