Ventline Ventadome Fan Motor Bracket

I wanted to add a fan to the existing Ventline Ventadome roof vent in my RV without having to replace the entire vent for at least $150 which is what I was told I had to do.
Instead, I bought all the parts I could. I designed and printed the motor bracket that Ventline doesn’t make. Installed everything and now have a fan in the RV roof vent for about $45.

You will want to print this in light colored (clear/white didn't absorb as much heat) ABS or PETG, ABS being the best choice for this app
