Ender 3 Z axis antibacklash nut, adjustable for direct drive setup.

thingiverse

This is a crucial part of my project (https://www.thingiverse.com/thing:4182312) focused on designing fully adjustable Ender 3 dual Z axis solutions. This component serves as a direct replacement for the standard Z nut carriage, excluding the extruder, ideal for direct drive setups. It enables adjustments in both the X and Y directions, ensuring the Z screw remains straight, aligned, and free from wobbling or binding while utilizing anti-backlash nuts. **Update** I've also incorporated a bracket to accommodate the stock nut into this design. As my motor mount, I employed this design (https://www.thingiverse.com/thing:2932344). To assemble this component, you will require one M5x45mm screw, two 5mm washers, two M4x10mm screws, and two M4 nuts. Additionally, you will need to drill a larger hole for the eccentric nut (7.2 mm) and rotate the X stepper motor as depicted in the image. Remember, precision is key when assembling this part, as its primary purpose is to enhance the accuracy of your machine. In the near future, I plan to design an updated version that incorporates an extruder mount. If you have any questions or concerns, please don't hesitate to ask.
