New Mainboard Cover, Wiring, Bearing Revamp, Heatset Inserts, Servo Cover

I added space for the mainboard segment, now it has clearance to actually fit, I redid the cover for this segment, and now it can allow the wires to come out

The servo mount now has heatset inserts, because the previous screw in print kept slipping out, but this time the screws just would not go into the inserts through the mount for some reason? The screws went in normally, but with the tolerances, when multiple screws go in they just fight and push against the edge of the insert instead of going in.

The MG996R servo housing now has been redesigned, based off of picture references and calipers to attempt to be more accurate than the last one to try and reduce the amount of bad tolerances affecting the gears and making them misaligned, reducing torque output.

And just general wiring and CAD work.
