<p>Update:</p><p>As suggested by @SLcoolK, I added this Roller Tensioner to the design to provide adjustable resistance to the rollers to prevent unwinding.<br>This printable spring can be added to the holder without reprinting the original parts, and the number of springs added depends on the desired resistance.</p><p>It is recommended to use fatigue-resistant materials such as PETG, Nylon, PC or PE to print the spring leaf to increase its service life.</p><p>This is an improved version of my previous design：<a href="https://www.thingiverse.com/thing:5280289">https://www.thingiverse.com/thing:5280289</a></p><p>The previous design worked fine until I bought some Polymaker filament with cardboard spools.</p><p>So I decided to redesign it to solve two problems with the previous design:</p><ol><li>Thin base brackets do not provide sufficient strength (slight sagging)</li><li>Two bearings are not compatible with all spools</li></ol><p>The current design:</p><ol><li>The roller will compatible with most of the spools.</li><li>Connected axles add structural strength, allowing for a thinner bottom bracket.</li><li>No support material printing.</li><li>Use the same two 608 bearings.</li><li>Use the same one preloaded M3 nut.</li><li>Available for 90mm (maximum spool thickness: 65mm) or 100mm (maximum spool thickness: 75mm).</li></ol><p>Two m3 x12 (at least 12mm) screws will be needed.</p><p>In case you own a Voron, I'm assuming you have some m3 heat inserts and you have the tools to insert them, so I added two inserts to the shaft. It's not a must have, but they will make the holder stronger.</p><p>I included two files (for 90 and 100) that do not contain the pockets for heat inserts, print one of them for not to bother with heat insert.</p><p>The bearing hubs on the roller are designed with large tolerances to allow bearings to self-align. I don't want to press the bearing into plastic, they may not be able to end up parallel</p><h3>Print Settings</h3><p><strong>Printer:</strong></p><p>Voron 0.1</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>15%~40%</p><p><strong>Filament:</strong></p><p>Polymaker Polylite PLA/ ABS</p><p>White+ Blue</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: 3D Printer Accessories</p>
