This is a design for the side air ducts on a Sling Tsi aircraft to split the airflow entering the plane. The intake slides over the naca duct, the front outlet has a 50mm diameter and the rear passenger side panel outlet is 88mm x 24mm.

The design has an internal splitter which sends 50% of the airflow to the back seat passengers via the side channel and 50% of the air to the front seat vents.

It has been designed to be printed with a wall thickness of 1.8mm from PETG for long term durability.
