The images (and CAD) show the 2 stage with a shorter output shaft than the 3 stage, which I assume is correct.
Any ideas for using the 3-stage shifter for a WCD/direct driven center wheel? The lower housing hex standoffs look like they will interfere with putting a 16T #25 sprocket on the drive axle to power the front/rear wheels. Turning the gearbox sideways would work, but that eats up >2" of ground clearance, meaning at least 6" wheels would be required.

As far as I've seen, to get a reasonably speedy robot, you need to use 6" wheels anyways. The ball shifter ratios really aren't built for direct driving 4" wheels. That said, the 3rd stage is really versatile. There are a a lot more options that you can get by switching out the 2 default 3rd stage gears ratios for different gears.
