Tricopter mount for smaller motors

Making a tricopter or duocopter (twincopter) or something that needs single-axis vectored thrust? Here's the solidworks and STL files for the redesigned mount for the smaller hexTronik 20gram motors I'm using.

These are the motors I've got:

Everything is parameterized in solidworks for easy modification, but this should fit mostly any motor of this size.
