Expandable Sample Spool (Library Edition!)

prusaprinters

<p>Official sample holder of <a href="https://filamentcolors.xyz">FilamentColors.xyz</a>! Based on the wonderful design by SubSite, this spool holder is designed to make your life easier when working with filament samples.</p> <p>This print-in-place spool holder is expandable to fit whatever size coil you're currently working with (or want to work with)! Locking tabs keep each of the three arms in place throughout a print while collapsing easily to remove or load filament onto the spool.</p> <p>The Library Edition is specific to <a href="https://filamentcolors.xyz">FilamentColors.xyz</a> -- we print hundreds and hundreds of samples, and loading and unloading filaments quickly is important.</p> <p>To load filament:</p> <ul> <li><p>Pick an arm, then thread one end of your filament through the hole next to the U shape that holds the coil. Fold the end of the filament so that it can't work its way out.</p> </li> <li><p>Place the spool into the middle of the coil, then expand out the first arm by one click.</p> </li> <li><p>Work your way around the spool, bringing each arm out one click at a time until the filament coil is snug.</p> </li> </ul> <p>The arms may not end up extended at the same amount when you're done -- that's perfectly fine! At the weights that this coil is designed to support (100g max), the hole being off-center won't hurt anything and it should work just fine.</p> <p>The Library Edition is based on the modified <a href="https://www.prusaprinters.org/prints/36621-expandable-sample-spool-holder">Expandable Spool Holder</a> by <a href="https://twitter.com/mad_monkey01">Jordon of Mad Monkey</a>, which in turn is based on the original version by <a href="https://www.prusaprinters.org/social/2448-subsite/prints">SubSite</a>.</p> <h3>Print instructions</h3><p>Tested with PLA -- no supports are needed beyond the ones that are included in the print by default. 0.2mm layers required.</p>
