                  1. Idler motor - rotates the idler.
                  2. Idler - contains five pulleys. By rotating the idler, a single pulley gets in direct contact with the filament and applies pressure on it. Then, the pulley motor can push the filament forward into the selector.
                  3. Left hardware button - moves the selector left.
                  4. Middle hardware button - preloads filament into the selected position.
                  5. Right hardware button - moves the selector right.
                  6. LED indicators - indicate the current status of the MMU (selected position, errors, etc.)
                  7. SuperFINDA (or FINDA for short) - MMU3 filament sensor built into the selector.
                  8. Selector - selects a filament slot by moving to the requested position. Filament is then pushed through the Selector into the nozzle by the Pulley Motor.
                  9. Fitting - There are two fittings on the front PTFE tube. The other one is mounted to the top of the extruder. The color of the fittings may vary.

                  1. Reset button - triggers reset of the MMU3 unit only.
                  2. MicroUSB port - for flashing MMU3 firmware via PC.
                  3. Pulley motor - rotates the pulleys that move the filament inside the MMU3 unit.
                  4. Selector motor - moves the Selector left and right.
