155mm to 90mm Range Hood Duct Adapter
This 90-degree duct adapter is designed to connect a range hood with a 155 mm internal outlet to a 90 mm internal ventilation duct.
The adapter features a smooth airflow transition with a gradual reduction to reduce turbulence and improve airflow efficiency.
The model is split into two printable parts, allowing it to fit smaller FDM printers. Both parts are connected using an integrated alignment joint for easy assembly.
