<p>Y-Belt tensioner for Prusa i3 Bear Full Upgrade MK3.</p> <p>2019-10-20</p> <p>I noticed that the tensioner side-part bent a bit over time.</p> <p>So I added a stronger version of it.</p> <p>2019-11-02</p> <p>Replaced the stronger version of the side-part with an even stronger one with 5mm thickness.</p> <p>2020-12-01</p> <p>Just noticed that the mk3 bear upgrade github repo provides a proper tensioner since Aug 18, 2019: <a href="https://github.com/gregsaun/prusa_i3_bear_upgrade/blob/master/printed_parts/common_to_all_versions/stl/y_idler_mount.stl">https://github.com/gregsaun/prusa_i3_bear_upgrade/blob/master/printed_parts/common_to_all_versions/stl/y_idler_mount.stl</a> <a href="https://github.com/gregsaun/prusa_i3_bear_upgrade/blob/master/printed_parts/common_to_all_versions/stl/y_idler_tensioner.stl">https://github.com/gregsaun/prusa_i3_bear_upgrade/blob/master/printed_parts/common_to_all_versions/stl/y_idler_tensioner.stl</a></p> <p>I'm currently sticking to my version though, since it is easier to print and the screw to adjust the tension is not facing to the inside, which makes it easier to adjust the tension.</p> <p>2021-04-29</p> <p>Added a new version for the part, which attaches to the aluminium profile since the old version tends to bend over time.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>CTC Prusa i3 Reprap MK8 DIY</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div> <p><strong>Infill:</strong></p> <p>50%</p> <p><strong>Filament:</strong></p> EFORINK PLA <p>Blue</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Make sure to print the parts in the correct orientation.<br/> Especially the mount should be printed lying on its side to have more strength against the pull of the screw used to tension the belt. </p></div></p></p> Category: 3D Printer Parts
