Ender 3 dual Z stepper mount
thingiverse
Full transparency, this won't work with Creality's V1.1.4 silent or V1.1.5 silent boards due to TMC2208 stepper drivers skipping steps badly. My apologies if anyone printed this before realizing there was an issue; it should work with the standard board. Dual Z stepper motor mounting system that requires no moving of power supply or display screen, just two parts need printing: you'll also need a second standard lead screw, lead screw nut, stepper motor, Y harness for twin steppers and a handful of fittings. The stepper mounts to the vertical 2040 extrusion right at its lowest point; the lead screw nut bracket mounts to the rear of the two outer V groove wheels using stock bolts. I found that the two M5 bolts on mine had an extra few mm thread length, which was enough for the thickness of the bracket. All four stepper mounting holes have a little wiggle room to help you align the lead screw nicely.
