You can download the CAD from their website and use those.

There are two versions of the bearing block - the gearbox version which features the block and one plate, and the outer wheel version, which contains a single block and a plate on either side. The gearbox version with only one plate has a part that mounts into the inner plate of the transmission, and the outer wheel versions with two plates are for the wheel slots that are powered by chain/belt.
