Prusa i3 MK2 X-Ends remake

prusaprinters

<p>I recently purchased some POM nuts from RobotDigg, but noticed they only had 3 mounting holes. Since I am running a custom MK2 clone, I wanted something close to the original with little modification,</p> <p>Enter the new x ends. This is a modification of the x-ends from the prusa openscad files to include a 3mm hole on one side (normal) and a 2mm hole on the other.</p> <p>With the help of a small hand drill, you can pop a new hole in the 3 holed POM nut without compromising its structural integrity.</p> <p>Needed:<br/> 2x POM nuts from RobotDigg. (25.4mm flange, 19.05mm center-to-center screw hole spacing, 12.7mm OD of throat for leadscrew)<br/> 2x m3x12 screws<br/> 2x m3 nuts<br/> 2x m2x12 screws<br/> 2x m2 nuts<br/> (+Other screws/parts/etc that make up the Prusa X-Ends)</p> <p>Included are my modifications to the x-ends.scad file, and resulting STLs for the ends. As well as modifications to the leadscrew covers with modified screws for TR8x2, TR8x4 and TR8x8 leadscrews.</p> <p>I also added in comments and variables for anyone wishing to tweak settings.<br/> You will need to grab a copy of the following files from the Prusa github:<br/> bearing.scad<br/> polyholes.scad<br/> x-end-idler.scad<br/> x-end-motor.scad</p> <p>Releasing under GNU GPL v3 as that is what the original scad files from Prusa are.</p> <h3>Print instructions</h3><h3>Category: 3D Printer Parts Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2rqZ6Uo">Prusa Clone</a></p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0.2mm</p> <p><strong>Infill:</strong> 20%</p> <h3> Post-Printing</h3> <p><strong>Drill a hole in the POM nut</strong></p> <p>Use one of the ends as a guide.</p> <p>Use a small 1/16in or 2mm drill bit and hand drill a hole in the POM nut after tightening down the m3 screw on the opposite side.</p> <p>Take your time, and mind the surface under the part (I may have put a hole or two into my counter top)</p>
