Prusa Bear Y Axis Linear Rail Modification - Old Design
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. The design for the bumpers was inspired/remixed from JuanPuchol on Thingiverse. Be sure to take a look at his edit, as he also includes a design for X and Z Rail Modifications.<br> </p><p>Parts Needed:</p><p>2 x V-Slot Aluminum Extrusion (331mm)<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>Extra:<br> </p><p>10 x M3 5mm (Users have found that 8mm works better)<br>10 x M3 T-Nuts<br>These can be added to create a stronger connection of the linear rails to the extrusion.</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><br>Inspiration from JuanPuchol on Thingiverse</p>
