Spool Holder with PC4-M10 PTFE Adapter

prusaprinters

<p>I love the space saving interlocking design and the ability to attach it to a shelf. &nbsp;After using it I decided to modify it for better integration with my current setup.</p><p>Changes from the original for my setup, maybe others will find them handy too:</p><ol><li>I added a PC4-M10 PTFE tube adapter to both sides (because I'd mount it wrong at least once).</li><li>On my shelf it echoed/clunked a little and I needed additional lift for the PTFE adapter. &nbsp;I created a TPU pad to cushion it. &nbsp;Super quiet now.</li><li>I never have luck with squared rollers. &nbsp;Something always happens and the spool gets off track. &nbsp;I changed from the square edges to a scalloped edge. &nbsp;This keeps the spool on matter which direction or how far it decides to wander.</li><li>Removed the need for supports by splitting the rollers in half so they can be printed flat.</li><li>Changed the diameter of the roller by 1mm for additional space to run the PTFE tube.</li></ol><p>Printing instructions for the roller:</p><ul><li>PLA</li><li>.2 mm layer height</li><li>3 Perimeters(shells)</li><li>Infill: 10%</li><li>Infill Type: Grid.</li><li>Supports: No</li><li>Assembly:<ul><li>Put the two flat halves together and use two 608zz bearing to hold it together.</li><li>Some for is required, but you should be able to do this by hand.</li><li>This mounts in the two groves on the Spool Holder Base</li><li>You will need four halves (two sets) of rollers per Spool Holder Base</li><li>You will need four 608zz bearings (same size provided with the Prusa MMU2s holders).</li></ul></li></ul><p>Printing instructions for the TPU base (you could also print in PLA or material of preference):</p><ul><li>TPU</li><li>.2 mm layer height</li><li>Infill: 15%</li><li>Infill Type: Grid.</li><li>Supports: No</li><li>Assembly:<ul><li>This mounts under the Spool Holder Base.</li></ul></li></ul><p>Printing instructions for the Spool Holder Base:</p><ul><li>PLA</li><li>.2 mm layer height</li><li>Infill: 15%</li><li>Infill Type: Grid.</li><li>Supports: Yes, painted enforced at both of the PTFE connector openings. &nbsp;They are easy to remove with a simple twist. (If you select everywhere in PrusaSlicer it should hit the correct areas as well).</li><li>Assembly:<ul><li>This is mounted on top of the TPU pad prior to attaching to the shelving with wood screws.</li><li>PC4-M10 adapter screws into either end. &nbsp;Finger tight, don't overtighten.</li></ul></li></ul><p>&nbsp;</p>
