Slew Drive remixed to allow for further integration in other projects

Some minor modifications to the original model:

1. Squared off the wormdrive housing to enable higher tolorence variance in the wormdrive print
2. Small cutouts on the wormdrive housing for bearings (2x Deep Groove Ball Bearings 6700ZZ Double-Shielded Thin Section Miniature Bearings 10x15x4mm (Amazon link))
3. Squared off the outside to allow it to be mounted to other surfaces easier
4. Reshaped the bottom wormdrive hole to be a rectangle for lubrication application
5. Added a gasket to be used between the two hull halfs.
