Filament stand using MM2 roller

prusaprinters

<p>We upgraded our printer at work to an MMU2, which came with a set of five spool holders and rollers. However, I modded the MMU2 with a <a href="https://www.printables.com/model/6605-prusa-mmu2-ptfe-holder-m10-passthrough-adapter">pass-through adapter</a> to allow for easier swapping between our various filaments. By redesigning <a href="https://www.printables.com/social/3114-mtb3r">MTB3R</a>'s spool holder to hold just a single roller, we can load 10 spools using only the equipment that came with the MMU2.</p><p>Printing notes: after a few unsuccessful attempts at printing these, I found that dropping the speed down to 50% from just before the inner arms meet to just after the outer arms connect resulted in a clean connection, which is what is programmed in the uploaded gcode (mouse ears added for lift prevention.)</p>
