120mm Exhaust Deflector (Exterior) for Venting

thingiverse

Updated with newer version that has rounded corners and a bit smoother surface set for airflow. Version 1 has held up fine thru two winters for me when printed of ABS. This is a deflector for use in a 3D printing ventilation system, preventing water or gusts to blow directly into the exhaust overcoming a fan. It is low profile allowing for mounting in a screened in window. Vanes start parallel to airflow, and turn to a 45 deg for supportless printing, and line of sight blockage. Airflow is relatively unaffected, except it is deflected down. For the lowest vane a cut out exists on the very bottom, printed fine in ABS without support.
