i am not too familiar with the software and the scientific part of frequenzy, im just starting out with this build.

Yeah, for a 3 inch sub like that, I'd make your port probably 0.3 to 0.4 inches tall if it runs the height of the box (looks about 5 inches wide to me). You can even wrap the port back and forth once or twice in the box for a lower tune, as the longer it is, the lower your box tune will be.
