Where can I get a CAD model for the Moto X I am attempting to make my own 3D printed case for my phone. I need either very specific dimensions or a CAD model of it. 

I've searched around but couldn't find anything.
In fact, one is available from Motorola here, posted by Reddit user troub (source). It is a .dae file but can be converted using Autodesk FBX Converter (see www.cadstudio.cz/download or www.autodesk.com/fbx). Alternatively, it is posted here on Thingiverse as a .stl file.
