URSA - Gearbox/Differential Tweeks

I printed out the URSA BEAR over the last few weeks. I just finished putting it all together, and have been fixing issues I've ran into as I go. My bearings were coming free, so I added a cage. My servos didn't line up to the holes, so I moved them 2mm over. Then my gears were slipping/not meshing nicely, so I widened the area around the main gear 1mm on the sides, to accommodate the 29T modified differential main gear.

(I experienced slipping and teeth grinding with the stock GB03 differential, which the person who made the 29T gear had noted as well. I included the 29T gear into this project, so everything is all together.)

UPDATE ON SLIPPING: I discovered the source of most of my issues: I didn't have any bearings in the differential, on the main axles. Just the 2 in the spindles. My input shaft to the gearbox only had 1 bearing too. After adding a second bearing there, and the 1 on either side of the axles, my gearbox meshes together much better.
