This shroud is intended for the right hand fan of the Mankati printer's print head. This shroud effectively guides the airflow around the peeks away from the print bed. Most of the airflow vents to the left. This needs to be used with the matching inlet shroud. If not the print heads fails to warm up to temperature, or may take longer depending on ambient temperature. Designed for a fan mounted angle of 23° of vertical. You may need to bend the mounting plate of the fan, or I can produce a new model on request if needed.
