Rat Rig toolhead fan shroud printed part

40x10mm 24V Axial Fan

The wires should be positioned where the arrow points.

4x M3x16 Cap Head Screw

Insert the M3x16 screws into the Rat Rig toolhead shroud printed part, through the 40mm fan, and fasten them into the Rat Rig toolhead front.

Take care not to over tighten the M3x16 screws as you can damage the printed parts.

Pay special attention to the fan airflow, it should blow the air towards the hot end heat sink. Most fans have a small arrow indicating the airflow. If not, the the fan label should be facing the hotend.
