OpenWheel V2

This makes some improvements over the original. No more centering jig. The collars are press fit plus shaft glue. No support necessary. Better balance. When exporting from Fusion, no longer need to bring wheels into meshmixer for rotation. In fact meshmixer is no longer necessary at all. Refer to the original write-up for collars and shaft glue. Read the original guide for info on how to tune your flywheels to your cage and desired "crush" (i.e. circle radius, hydrostatics are cool). As before, I recommend the fusion route over customizer if you can handle it. Sketches that should be modified to your needs are named.

I will eventually update this to be more descriptive but I'd rather work on more content atm. The first guide had a lot of worthwhile reading and is mostly applicable still.
