Thrustmaster T150/TMX Hardmount Fixed

A friend asked me to print this for him but there were a lot of issues with the original model that I had to fix:

- Wasn't flat on the bed
- Nut holes were too big (as per another user's comments)
- M6 screw holes too big
- Added a cutout in the middle to save material; it actually reinforces it.
- Numerous extra holes extra bits / mesh errors

This is the fixed mesh from an hours' tweaking.
