⬢A cardboard box for use as a heatbed protection during the assembly. Hint: use the Prusament box.
⬢Manually move the X-axis assembly all the way to the front side of the printer.
⬢Move the extruder approximately to the center of the X-axis.
⬢If you have loaded the filament, unload it from the hotend. On the screen, navigate to Filament -> Unload Filament.
WARNING: The hotend and heatbed are very HOT. Do not touch these parts!!!
⬢Remove the filament from the hotend. It is not necessary to completely remove it from the printer. Just a few centimeters (inches) above the extruder.
⬢Before you proceed, it is recommended to protect the heatbed.
⬢Make sure the heatbed is cooled down to ambient temperature. Place the empty cardboard box approximately to the front center part of the heatbed.
⬢Loosen the M3x14 screw of the dwarf-cover-door.
⬢Lift the dwarf-cover-door to access the electronics board.
⬢Cut the zip tie that is holding all the cables in place (be careful not to damage any of the cables while doing so).
The connector has a safety latch. It is necessary to press the latch before disconnecting. Otherwise, the connector may get damaged.
⬢Disconnect the print fan cable.
⬢Release the M3x14 screw of the print fan's plastic cover.

⬢New print fan (1x)
⬢Zip tie (1x)
⬢Place the print fan on the X-carriage.
⬢Lead the print fan's cable as shown in the picture.
⬢Connect the print fan cable to the Dwarf board.
Do not overtighten the zipe tie! Otherwise, you can break wires.
⬢Guide the zip tie around all extruder cables except for the hotend heater cable and hotend thermistor cable and slightly tighten it.
⬢Place the extruder-plate into the cutout area and make sure the screw holes are aligned.
⬢Secure it with three M3x10b screws.
⬢Then secure it with two M3x40 screws.
