Sample coil spacer for under shelf rewinders
prusaprinters
<p>I love using the original <a href="https://www.prusaprinters.org/prints/2274-mmu-under-shelf-auto-rewind-spool-holders">Under Shelf Rewinder</a> from INeedOneDesigns, and my own subsequent <a href="https://www.prusaprinters.org/prints/138889-mmu-under-shelf-auto-rewind-for-25kg-spools">remix for larger 2.5kg spools</a>. However loose filament coils, such as samples, have a tendency to jump off the sides of the rewinder spool, and tangle up. This simple spacer slides over the end of the rewinder spool, gathers the coil together, and adds raised sides to keep loose filament from getting bound up. </p><p>Multiple spacers can be used at once, to hold multiple coils. Handy for just burning through extra samples with an MMU or Palette.</p><p>I originally used a smaller diameter for the sides, but found as coils loosened up, they could get wrapped around the smaller diameter sides.</p><p> </p>
