Goal was to mount some cool real car air vents for better immersion, bought several round types but ended up using the Alfa Romeo 147 ones as they looked the coolest.
Wind Sim shroud is designed to fit this particular air vent. Originally I added the wind tunnel later so it is separate part, but also now I provided a single part shroud + integrated wind tunnel. This design provides very high airflow with no backflow due to the wind tunnel.
Adding rear car vent allows for better airflow adjustment as it not only has fins, but also rotates.
The decorative trim ring has no other function than to give the product more finished look. It was remixed from here: https://www.thingiverse.com/thing:4508896
