⬢First, slide the fan in the Fan-shroud and make sure it is aligned properly.
⬢Second, fix the fan in place using one M3x20 screw. Tighten carefully, or you will damage the fan's casing.
⬢Turn the extruder around and insert the M3n nut. No need to pull it in, we will use the screw.
⬢Place the remaining M3x20 screw from the other side and tighten it, but carefully, or you will damage the fan's casing.
⬢Guide the cable according to the picture in the channel. Bend it slightly towards the extruder. DON'T stretch the cable!
