Ender 3 Dual Z Axis Mod

thingiverse

I designed a dual Z axis mod for my Creality Ender 3, but I wanted it to look similar to the CR-10S's design. Since there was one available, I edited and borrowed files from the CR-10 OEM - Complete 3D Model, CR-10 Dual Z-Axis Belt Synchronizer, and Parametric pulley - lots of tooth profiles on Thingiverse. I'd like to thank these creators for their contributions. This mod helps keep my Z axis and X axis trammed, which is a big plus if I decide to try direct drive on my printer later. I printed my flange lead screw nut and used a heated lead screw to thread it, but I'm replacing it with a metallic one from AliExpress. The printed version functions as expected without any issues. Below are the additional items I purchased for this mod, which can be found at affordable prices on AliExpress: 1.
