I'm exploring how the fat tires will actually mount to the CV axle. Turning down the splines on the axle seems like a waste to me. But to use them, I'd need some kind of spline hub that would attach to the fat tire hub. This could be the first part that I send to NanoAL. They are aluminum 3D printers!
3D printing in aluminum is just cool and I've been hoping something on this project would fit the bill. To make the model, I measured the width of the teeth and gaps of the splines and modeled the spline profile in Fusion360.

To make sure this profile fits IRL, I printed a test piece in PLA and fit it on the CV axle.
It's almost perfect. There is a very slight wiggle, so I'm going to adjust a bit and print a few more until it's dialed in. Then, I'll add a flange, so it can attach to the fat tire hub. Once I have a working plastic prototype, I'll contact NanoAL to print it in aluminum.
