Not Gears Direct Drive System

Bolts, nuts and bearings are not included since I don't own those designs; they are easy to find on the internet though. Only 2 types of bearings are used in the assembly: 61810 (big) and 61900 (small); beware of counterfeit bearings!!

Materials suggestion: 45xx steel or stainless for "motor tube" and "motor wall"; 42CrMo x hardened steel for the axle; 7xxx or 6xxx series aluminum for the other parts.
The project is in very early stage and I disclaim all the responsibilities for any damage caused by the use and misuse of the provided designs.
