<p>This simple filament spool holder is based on the original ones shipped with the MMU2S upgrade, however in a smaller form to fit five of them in a common plastic (almost) dry container.<br/> Although there are many amazing holders and dry boxes out there, I was looking for something very simple, low cost, and easy to use solution.</p> <p>The holder reuse the bearings and aluminum bars that come with the upgrade. The (almost) dry box serve also as filament buffer and the system is design to minimize frictions especially if it is combined with the "MMU2 PTFE Holder M10 Passthrough Adapter". <a href="https://www.prusaprinters.org/prints/6605-prusa-mmu2-ptfe-holder-m10-passthrough-adapter">https://www.prusaprinters.org/prints/6605-prusa-mmu2-ptfe-holder-m10-passthrough-adapter</a></p> <p>It will needed to cut the aluminum bars at 95-98 mm and the tips from the yellow stoppers. The dry box has internal dimensions at the top: 52x35x41 cm.</p> <h3>Print instructions</h3><p>You can print them with your favorite material and settings depending the desired finishing.<br/> Up to three parts can be fitted on the MK3S hotbed.</p>
