RatRig Vcore-3 MGN9 carbon gantry

prusaprinters

<p>Here is my design for mounting a carbon square tube and MGN9H rails on RatRig Vcore-3.</p><p>This also solves some issues while tightening XY joiner plates and pulleys/idlers alignement.</p><p>Note1: New XY joiners can be used on it’s own with original 2020 aluminium extrusion but you still need shoulder screws.</p><p>Note2: Original MGN12 linear rail can be retained if you are not looking for big weight reduction. Simply drill carbon tube accordingly</p><p>[20220313] Added reinforced X_endstop that come flush with XY left joiner (only for use with MGN9).<br>[20220624] Increase tolerancy on Carbon tube insert for better fitting with nylstop nuts</p><p>XY joiners rev1.1: aesthetic change plus weight reduction</p><p>---Parts---</p><ul><li>Left/Right XY joiners (printed)</li><li>4x <a href="http://aliexpress.com/item/1005003335259903.html">Shoulder screws D5x50mm M4</a> + nuts</li><li>4x M5x30mm socket head screw</li><li>2x M5x10mm socket head screw</li><li>carbon tube insert (printed)</li><li>6x M5x7x6mm brass inserts</li><li>2020 carbon square tube</li><li>MGN9H linear rail</li><li>X_endstop_MGN9H (printed)</li></ul><p>---Tools---</p><ul><li>Drilling guide (holes for XY joiners) (printed)</li><li>MGN9 aligning tool (printed)</li></ul><h3>Print Settings</h3><p><strong>Printer:</strong></p><p>RatRig Vcore-3</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>No</p><p><strong>Resolution:&nbsp;</strong></p><p>0.2</p><p><strong>Infill:</strong></p><p>30%</p><p><strong>Filament:</strong></p><p>/ ABS/ASA/Nylon-CF&nbsp;</p><p><strong>Notes:</strong></p><p>Layer height: 0.2<br>Perimeters width: 0.45<br>4 perimeters</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: 3D Printer Parts</p>
