Gravity Spoolholder Nut for cardboard spools
prusaprinters
<p>I needed a medium size nut to fit cardboard spools with a hole width of 56 mm diameter.<br>With the default nuts in <a href="https://www.prusaprinters.org/social/11-michal-fanta/about">Michal Fanta</a>'s <a href="https://www.prusaprinters.org/prints/10370-gravity-spoolholder-for-mmu2s">Gravity spoolholder for MMU2S</a>, my cardboard spools hit the bottom edge of the spoolholder, preventing them from rotating freely.</p><p> </p><p>I also use these nuts on my <a href="https://www.prusaprinters.org/prints/116362-prusa-spool-holder-centering-sleeve">Prusa spoolholder centering sleeve</a>. With this medium sized nut, cardboard spools are centered nicely and rotate evenly.</p><p> </p><h4>Print Instructions</h4><p>I suggest to print these nuts with 0.15mm layer height and 15% infill in PETG, but PLA will probably do just as well.</p>
