This part replaces the stock top extruder plate of the Flashforge Creator Pro. It improves the clamping of the wire bundle to the extruder and improves the interface between the filament guide tubes and the extruder.
Installation is simple, cut the cable tie that holds the wires to the spacer, remove the two M3 screws (note the different screw lengths, 15mm vs 20mm) carefully remove the stock plate (you can disconnect the two stepper motor connectors but no need to cut any wires or to take apart the extruder), place the new plate, secure the cable bundle to the cable clamp using cable ties and secure the plate to the extruder top with two screws. Preferably replace the longer screw with a M3x15 screw, similar to the other one but if you don't have one, use the M3 spacer that is printed with this model to match the screw length.
My printing setup: ABS, 110C bed, 230C nozzle, 3 shell layers, 25% infill, slicing with Simplify3D.
