CR-10 Anti-Wobble Z Pedestal for Stock Bearing and Helical Beam Coupling

thingiverse

I modified the Ender 3 and CR-10 "Z" axis motor mount by 3Dthingsmaker to fit my CR-10 with T-Bracket and house the stock radial bearing that came with my CR-10 Mini. After watching a YouTube video by AletheianAlex, who explains z-wobble and its best solution, I gained valuable knowledge. This is AletheianAlex's locking collar; however, I had to scale mine up to 106% to fit snugly on the leadscrew, which was challenging due to my use of cheap PLA. A washer is also required to sit between the stock bearing and locking collar. For installation, you will need to put a coupling on the motor before inserting it, which can be a bit of a pain. In my previous version, the screw holes for the motor didn't line up perfectly, so I had to drill them out slightly. The updated version has larger holes to avoid this issue. If you encounter any problems during installation, feel free to let me know!
