Bear Linear Rail Y Axis Modification

prusaprinters

<p>This design allows for quieter operation, but also significantly improves stability and rigidity of the y axis. For a double linear rail design, it is important to not over constrain the carriage in order to allow for smooth operation.&nbsp;The design was inspired/remixed from JuanPuchol on Thingiverse and the Rail Holder is a slight modification from Chris Warkocki on GitHub. Be sure to take a look at their respective designs. They work really great as well.</p><p>When assembling, please follow these instructions:</p><ol><li>Attach Rails to VSlot Extrusions</li><li>Put Bearings on Rail and Screw in the Spacers with Countersunk screws</li><li>Put on the Y Carriage and Screw in final screws</li><li>Place Extrusions and Y carriage assembly into the frame and align with the aligner.</li><li>I suggest putting on the Rail Holders first and then screwing on the angle corners afterwards</li></ol><p>Parts Needed:</p><p>2 x V-Slot Aluminum Extrusion (330mm)<br>2 x Linear Rail (350mm - C)<br>3 x MGN12C Blockz<br>6 x M3 12mm<br>6 x M3 6mm Countersunk Head<br><br>10 x M3 5mm (Users have found that 8mm works better)<br>10 x M3 T-Nuts</p><p>8 x M5 8mm (Users have found that 12mm works better)<br>8 x M5 T-Nuts</p><p><br>Prusa Bear Printer Design by gregsaun<br>https://github.com/gregsaun/prusa_i3_bear_upgrade<br>&nbsp;</p><p>Rail Holder Design - Small Modification from Chris Warcocki design https://github.com/codiac2600&nbsp;</p>
