Stanley Infrastructure used to machine wheel shafts out of a single block of steel. Because of the
diameter of the flange and the length of the shaft, this meant that ~90% of the stock material was wasted in each part.

By purchasing an off-the-shelf shaft and key, they were able to easily print the more complex flange on the Metal X. The new assembly passed both durability and abuse drop testing.
