Exaust Air Blower Outlet

thingiverse

People assemble the exhauster with a duct diameter of 100 mm. Airflow causes the lamellar to open and then only closes due to gravity. This method is simple yet highly effective. Two countersunk head screws, 3.0 by 2.5 mm in size, are required to attach the assembled parts to the outlet housing. Four screws with a minimum length of 3.5 x 45 are needed to securely fasten the complete assembly to the wall. The overall dimensions of the assembly measure 140 by 140 by 65.
