Rewinder spool holder

prusaprinters

<p>I wanted the ability to change spools out easily while also using the integrated rewinder to keep multi-material prints from turning the RepBox into a SpaghettiBox.</p><p>&nbsp;</p><p>I tried several designs to support changing just the spool and axle, but I always had problems threading the spools in and losing control of the axle or rewinder parts. &nbsp;I ended up on a holder where I can do all the fiddly bits of changing spools outside the RepBox and then move the whole assembly inside the RepBox. &nbsp;Along the way of getting to that solution I also got frustrated enough with the limited motion of the RepBox door and found life got a lot happier with the RepBox on its back.</p><p>&nbsp;</p><p>So here we are, a stand-alone holder for spools with the Integrated Rewinder that lets me fit 5 inside the RepBox. &nbsp;A tall and short version are available, I think the short version would be best for most people but I like the extra length on the handle with the tall. &nbsp;Flourished with an outline of the lion from the Czech coat of arms on the bottom. &nbsp;</p><p>&nbsp;</p><p>No special settings, no supports needed. I printed mine with a 0.6 nozzle and 0.3mm layer heights, everything should work with a standard 0.4 nozzle and 0.2mm heights. &nbsp;Some infill helps keep the walls rigid, the default 15% works great for me.&nbsp;</p><p>&nbsp;</p><p>Special thanks to Vincent Groenhuis <a href="https://www.prusaprinters.org/social/46-vincent-groenhuis">https://www.prusaprinters.org/social/46-vincent-groenhuis</a> &nbsp; and his Integrated Rewinder <a href="https://www.thingiverse.com/thing:3781815">https://www.thingiverse.com/thing:3781815</a> . &nbsp;My holder is designed to accommodate an 86mm wide holder.&nbsp;</p>
