Filament Roller for Prusa MMU2

thingiverse

I designed this filament roller by merging the best features from two different sources: Peter Rasmussen's Prusament Filament Holder and Paul Meyer's Prusa Research MMU2 Improved Roller. I reused several STL files from the second source while using the first one as inspiration to create a significantly reduced-friction system compared to the original rollers shipped with the Prusa MMU2. To make one roller, you need to print four main components: two side pieces, two connector pieces, four bearing standoff pieces, and four endcap pieces. Additionally, you'll require: * Two 85mm Schedule 40 PVC pipes with a 1-inch diameter (available at your local hardware store) * Four bearings (you can reuse these from the Prusa MMU2 rollers) * Two aluminum rods (you can also reuse these from the Prusa MMU2 rollers) You have the option to print label pieces if you want numbers on your rollers. To assemble the roller, start by connecting two connectors onto one side piece, followed by attaching the other side piece on the opposite side of the connectors. Next, insert cap pieces on both sides of one PVC pipe, then add bearings, aluminum rods, and bearing standoff pieces on either side, finishing with the two cap pieces at each end. Repeat this process for the second PVC pipe, and finally place both in the grooves of the roller.
