Prusa MMU2 Filament Retract Bank

thingiverse

My Filament Retraction Bank for the Prusa MMU2. I designed this to be Universal, mount any way, linear side by side, or stacked. Any direction, filament fed into it from either direction. large diameter roller, so no small radius for filament to follow. Easy loading by pushing up on the load lever, when loaded pull the lever down to allow filament to be retracted into the column.bank. Parts print easily, no supports needed. See MMU2 Retract Bank.pdf file for full descriptions and instructions. Note plate layout picture for orientation of parts. Some of the stl's came in oriented wrong for printing! Added filament guide that snaps onto Rubbermaid wire shelving in picture. Note, wires of shelves are not really accurately spaced, some bending may be required for plastic guide to properly snap on. Guide uses M5 to 4mm push in pneumatic fittings.
