Car Windshield Defroster Fix/Help

This model is mainly thought of because my car defroster stopped working and the windshield would be foggy. So this was created to stop that. The design is made to push air towards the top of the blower to the windshield.

I printed without supports but you can use them if you don't want any issues or a not good looking print.
