Hypercube x y motor mounts improved and STRONGER

prusaprinters

<p>This is a re-design of the X Y motor mounts for the Hypercube. In my opinion the original motor mounts were not strong enough to combat the forces from the tight belts. My goal was to make them rock stable and strong, and not worry about how much plastic they consume. I have done that. Mine have been installed for a few weeks now under belt pressure and there is no sign of bending, twisting or other fatigue. If you decide to use them you will also need my re-designed Y rod holders (<a href="https://www.thingiverse.com/thing:2230374">http://www.thingiverse.com/thing:2230374</a>) and Y endstop (<a href="https://www.thingiverse.com/thing:2230378">http://www.thingiverse.com/thing:2230378</a>) . They are both available as separate remixes.</p> <p>These motor mounts are designed to tight tolerances to fit the motors tightly and aid in preventing movement. Your printer should be calibrated well in order to print these.</p> <p>Each motor mount is secured to the 2020 extrusion using 3 M5 bolts. One bolt goes inside the motor mount, right next to it, and there is very little clearance, although it does fit, it rubs a tiny bit. Choose a M5 for this location that has a small head size. I found based on length and manufacture the head sizes varied quite a bit and chose the smallest I could find. Install the M5 bolt inside first, then put the motor in and the 4 motor mount screws. You can not insert the M5 after the motor is mounted. You can however stick an allen wrench in to tighten the screw once the motor needs to be mounted.</p> <p>Enjoy. Plenty of pics and the original source Sketchup files are included here.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Prusa Clone</p></div> <p><strong>Resolution:</strong></p> <p>.4</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>80</p></div> <p><strong>Notes:</strong></p> <p>Printed at .4 and 80% for strength and to minimize print time.
