This is the front of a Vortice Model 11630 exhaust fan. It holds the motor and the power connector. I have not put in all the redundant clamps, etc and I did not add in the (presumably) cooling duct, but I left the cable entry from connector to motor open so it should get airflow.
There is a step file so you can make your own changes to suit.
The author marked this model as their own original creation.
