This is a re-design of The Cabra skid and transmission case to make it easier to print and work with.
The new design has a 4-piece configuration, allowing easier assembly and stronger attachment. The transmission case also has a better gear mesh setup and a bit more space to allow the gears to spin super smoothly. The front motor mount was re-design to allow more pinion gear options and easier attachment of the motor.
All the pieces fit together very tight, like a puzzle. Little trimming might be required.

The motor mount should be printed standing with support, everything else just laying down. If you want a better finish, remove the support from the bridge areas and only leave for hangups.
Very important: precision is key for these parts to work properly. Make sure that your printer is printing accurately at the 0.1mm level. For example, most FDM printers will use plastic that will shrink while printing, resulting in a slightly smaller part. Just 0.1~0.2mm smaller and the gear mesh will not be perfect. Print and measure your part, if it's 1~2% smaller than the model, then print by increasing the size in the slicer 1~2%.
