I tried another spool winder but found it finicky and delicate.I designed this winder from scratch to be simple and robust, using the same self reversing leadscrew mechanism found on industrial cable windersWhy pick this model:<ul><li>Prints on a single build plate</li><li>Doesn't require heat set inserts or exotic hardware</li><li>Fusion and STEP files are available, remixes welcomed</li><li>Generous clearances, simple mechanisms</li><li>Designed to be a tool, not a project</li></ul>Print time:<ul><li>~500 grams of filament</li><li>~22 hours on Bambu Lab X1</li><li>~5 minute assembly</li><li>~2 minute spool transfer</li></ul>Hardware requirements:<ul><li><a target="_blank" href="https://www.amazon.com/s?k=608+bearings" rel="nofollow noopener">14x 608 skate bearings</a></li><li>A scrap of PTFE tubing</li><li>An electric screwdriver or drill with <a target="_blank" href="https://www.homedepot.com/p/DEWALT-MAXFIT-3-5-in-2-Philips-Bit-DWA3PH2MF/309474882" rel="nofollow noopener">a bit cut from ¼ inch hex stock</a> (most <a target="_blank" href="https://www.amazon.com/ITP1201-SCRWDRVNG-2IN-1-IMPAC/dp/B01LZZ7AOS/" rel="nofollow noopener">cheap quick change Philips bits</a> in the US fit this requirement)</li></ul>Print settings:<ul><li>Any.
