Minimalistic cr-10 dual Z
thingiverse
This is my attempt at a low-cost and simple dual Z mod for the CR-10. I haven't tried this yet, I'm waiting for my lead screw. My BOM 1 x 608 ball bearing (top lead screw mount) 2 x 625 ball bearing (bottom lead screw mount) 1 x 5 to 8mm flex coupling. 1 x M5 20mm bolt (bottom mount to secure coupler to bearings) 1 x M5 nut (see above) 3 x M5 50mm bolts, 40mm would probably work too (X gantry plate) 1 x 500mm lead screw (best option might be 2 x 600mm. This way you can keep full Z height) 1 x lead screw nut 1 x GT2 belt. (I couldn't find a closed loop in the right length, so I just spliced my own, more info below) I'm using gantry plate from this model https://www.thingiverse.com/thing:2335916. Belt splicing jig and info.https://www.thingiverse.com/thing:1827260. I ended up just using flexible super glue and no pins, and it seems to be strong enough, If I forgot something, leave a comment and I'll try to fix it.
