For the wheel that is direct driven from the gearbox, did you place the inner of the two Hex VersaHub towards the center of the robot from the inward-most sprocket?

The reason I am asking is that I was thinking about the alignment of the sprockets since in a setup like this only directly driven wheel needs the two Hex VersaHubs while the other two need the bearings which do not add to the "stack" of the VersaHubs and Sprockets.

Maybe a render of the direct-driven wheel would be easiest to understand. Also are you planning on machining the output hex shaft to a certain length to fit your design?

I'm trying to find an angle that'll show things a bit better. This doesn't actually directly drive any of the wheels; it uses a two-stage ball shifter with two sprockets on the output shaft. The ratios available on the ball shifter don't really work to my liking for directly driving 4" wheels.

Were I to direct drive, I think I'd put the hex hub on the far side of the wheel and stack the sprockets and bearing hubs up on the other, otherwise the thickness of the hex hub's flange would throw off the stack up for the other wheels and your wheels would be slightly out of alignment.
