Yet Another Spool Holder

prusaprinters

<p>Yes, I know, another spool holder, very original. It was more of a modelling exercise as I got more comfortable with CAD, and saved me the effort to get the necessary bolt for any of the existing models. Hopefully, it meets your need as it met mine.</p><p>It all started with a small spool of filament with the centre hole too small for the standard Prusa i3 mk3+ spool holder. <a href="https://www.thingiverse.com/thing:996398">PHIL</a> was my first spool holder back when all I had was the shiny new printer and the PLA it came with. I also took a lot of inspiration from <a href="https://www.thingiverse.com/thing:2047554">TUSH </a>and <a href="https://www.prusaprinters.org/prints/62910-latest-version-spool-holder-for-prusa-mini-flexibl">Copanko</a>. I'm sure you can spot the influences in the design.</p><p>&nbsp;</p><p>You will need to print</p><ul><li>4x Feet Pad</li><li>2x Slide Rail</li><li>4x Spool Wheel</li><li>1 of each of the rest</li></ul><p>The material shouldn't really matter for this, PLA should be fine. I did use TPU for the feet pad in an attempt for some nice and soft rubber feet, but the TPU I had was stiffer than I thought. Maybe you will have better luck.</p><p>In addition to the printable parts, you will need</p><ul><li>5x 608 bearings, for each wheel and the leadscrew,</li><li>4x M3x16 bolts and nuts</li><li>4x M2x16 bolts and nuts for both ends of the leadscrew assembly</li><li>4x M2x8 bolts and nuts for the slide rails</li><li>4x M2x8 bolts and nuts for the feet</li></ul><p>I know it is hard to tweak STL, so I have included the STP file if you want to make any changes to suit your need. If you prefer the original Inventor Assembly file, let me know.</p>
