<p>Filament load/unload issues? MMU2 taking too much space? Not with this Sisyphus Auto-Rewind spool holder! It keeps filament on the spool during unloading, up to almost three revolutions.</p> <p>Use two curved nuts to attach the spool to the roller. Put roller on stand. Insert filament in extruder/MMU2. That's all!</p> <p>A filament tube can be installed from extruder/MMU2 to the frame in two ways: above (using tube holder) or below the spool.</p> <p>The slope of the track can be adjusted by placing objects under the frame and/or by screwing two M3 bolts in the designated holes in the frames. This has a direct influence on the rewinding torque.</p> <p>Video: <a href="https://youtu.be/8nZiOu8y_jY">https://youtu.be/8nZiOu8y_jY</a></p> <p>This is the single-material version.
