The Better And Simpler Spool Holder

<p>All credits to Voron Design and boubounokefalos (links below)</p><p>(if you're either one of then and dont want to see this here msg me and i delete it)</p><p>&nbsp;</p><p>13.02.22 updated spoolholder radius on the top section to prevent the spools from rubbing on the printed parts</p><p>19.01.22 added sidemount option for anything. (shelf in my case)</p><p>&nbsp;</p><p>&nbsp;</p><h3>Rant ahead, just skip to the next headline</h3><p>Kinda shocked about the available spool holder and for the effort they take it isnt really superior than a piece of PTFE tube. The cheap bearings you buy are so packed with grease the spool likely rolls itself on the roller surface IF its not falling off.&nbsp;</p><p>I srly had so much pain and suffering ..</p><p>Dont misunderstand me, I also use dry boxes with large rolls having a bearing at each end.<br>(use the one where the front is raised, this helps when to spool gets empty)<br><br>But yeah opening bearings and removing the grease and give them a good spin with a handmotor until they actually work how the are supposed to be is pain. &nbsp;<br>(I now buy the ones with plastic sides, i think PETG)&nbsp;</p><p>There will however come time where you have this almost empty spool you should replace before the next print.&nbsp;<br>Yes run out sensors work but restarting a print at a shitty time sucks too and is visible.</p><p>I put mine in one of the plastic bags that came with the Geeetech spools and throw in a fresh silicate bag from the new one. Putting a single spool for an half hour print on the holder is way better then fiddling with dry boxes or having 4 slots occupied with the same color but almost empty.<br>&nbsp;(also hard to gauge through the plastic how much is left)<br><br>Pro tip: Do some multiple color wallart prints from time to time.</p><p><br>My issue with the bearing on top or next to the printer is that they “slip” and often unwind too much filament. (which is imho worst then the spool rolling on the PLA)</p><p>&nbsp;</p><h3>What and how to Print and assemble</h3><ol><li>Download the spool_holder.stl and a *_spool_holder_base.stl matching your aluminium extrusion, Ender 3v2 is 2020_extrusion<br>I think the 2020 is fine on any printer unless you prefer aesthetics but i also wanted to credit the original source so why not offer the stl too&nbsp;</li><li>Prints etting (recommended, but feel free to adjust)<ol><li>Perimeter: 3+</li><li>Top/Bottom: 5</li><li>Layer Height: ~0.3 &nbsp;(0.2 is fine to but takes way longer)</li><li>Infill: 31% Gyroid &nbsp;or &nbsp;42% Grid, &nbsp;dont cheep out</li></ol></li><li>push the two parts together</li><li>stick a part of &nbsp;3mm PTFE (the cheap white hard ones) in the holes of the spool_holder.stl<br>(the spool is basically sliding on it)</li></ol><p>btw i hope you have a ballend hex key, one screw is kinda hard to reach with the long end.<br>&nbsp;</p><h3>Credits</h3><p>&nbsp;</p><p><a href="https://github.com/VoronDesign/Voron-Switchwire">https://github.com/VoronDesign/Voron-Switchwire</a></p><p><a href="https://github.com/boubounokefalos/Ender_SW">https://github.com/boubounokefalos/Ender_SW</a></p><p>hymness1 VS.182 (Patrice#2063) @ Voron Discord&nbsp;</p>
