2020 Extrusion Lead Screw Bearing cr10

thingiverse

Mounts an 8mm bearing (608zz) to 2020 extrusion like the cr10 requires two m3 20mm screws and t nuts. For a full dual z upgrade: You'll need these parts: 500mm threaded rod t8 with 2mm pitch and nut Three m4 40mm nuts and bolts Nema 17 stepper motor Z coupler Eight m3 10mm screws Two m3 20mm screws (four m3 20mm if you want to replace the stock bearing on the opposite side) Six m3 nuts (eight m3 nuts if you want to replace the stock bearing on the opposite side) One 8mm 608zz bearing (two 608z if you want to replace the stock bearing on the opposite side) https://www.thingiverse.com/thing:2787543 https://www.thingiverse.com/thing:2800535 (4x) (6x for the other side) https://www.thingiverse.com/thing:2677626 Note: The m3 screws are not the same size as the stock screws and therefore they leave some wiggle room in the hole for the wheels but it's not a big deal. I printed some spacers and screwed them over the screw and hammered the wheel on top of it- it's optional and doesn't affect print quality. Image attached: You'll also need some washers for the bracket, they need to be spaced 9mm from the wheel (I guess you could print them too!).
