Base I made to connect a common rectangle to oval ventilation piece to my Mercury Plus hood.
It also got some small holes to let fresh air flow in.

Just be sure to measure dimensions when ordering your plastic rectangle to oval tube connector.

You'll also need to put a piece of tape of some sort over the security sensor on the back of the machine. Otherwise it won't start because it thinks the hood is off.
Just don't forget to put the hood on before pressing start.
Use at your own risk!
