The gearbox is designed for high loads loads and with the two tapered roller bearing can handle very high bearing loads in all directions.
Though the gearbox can be fully 3d-printed, I recommend using JLCCNC for machining at least the cycloidal disk as output. Their prices are really good and my parts turned out amazingly.
If you decide to print all the parts, you will lose some rigidity, longevity and torque.
All the instructions on how to build the drive and the necessary bearings can be found in this article:
