I have noticed that the AM wheel included in the KoP has a slant to the tread. The slant seems to be a design feature rather than a manufacturing defect since it is clearly on the prints
here. In other words, the slant is intentional and thus must have a purpose. My question is what is it? Also, what it the intended orientation of the slant with respect to the drivetrain (i.e. slant in or out)?
