Ender 3 - Z-Axis Stepper Damper Adapter

prusaprinters

<p>After installing a BLTouch on my printer, the bed leveling process highlighted its need for a z-axis stepper damper. I searched around, and was not satisfied with anything I found. So, I created a model of my own. The only downside of this, is that it requires a couple screws that are not found in common screw sets.</p><p><strong>Updates</strong>:</p><p><strong>2019-03-26</strong> - Added version that plays well with the Ender 3 Pro</p><p>Also, check out these other mods that dramatically reduce the sound of your Ender 3</p><ul><li><a href="https://www.printables.com/model/187665-ender-3-x-axis-stepper-damper-adapter">X-Axis Stepper Damper</a></li><li><a href="https://www.printables.com/model/187667-ender-3-y-axis-stepper-damper-v2">Y-Axis Stepper Damper</a></li><li><a href="https://www.printables.com/model/187670-ender-3-low-profile-feet">Low Profile Feet</a></li></ul><p>Enjoy the silence...</p><h3>Print Settings</h3><p><strong>Resolution:</strong></p><p>0.2</p><p><strong>Infill:&nbsp;</strong></p><p>30</p><p><strong>Notes:</strong></p><p>3 x wall thickness</p><h3>Post-Printing</h3><p>Required:</p><ul><li>1 x NEMA 17 Stepper motor damper</li><li>2 x M3*30mm screws</li><li>2 x M3*6mm <a href="https://www.aliexpress.com/item/50pcs-M3-6-8-10-12-16-20-25-30-mm-flat-head-countersunk-head-black/32966886940.html">flat head screws</a></li></ul><p>Steps:</p><ol><li>Power down printer</li><li>Remove wires from z-axis stepper</li><li>Remove 4040 aluminum extrusion end cap</li><li>Slide the printed mount onto the end to test the fit</li></ol><p>(slide on and off until it doesn't stick) 5.
