I prefer at least 3 layers of MDF where the port hole is and a VERY tight press fit, then silicone. You can also screw through the port into the MDF and add another support towards the end of the port.

you should paint the pvc. Black would look better than the white

i first used epoxy putty to bevel the outter end.. then used liquid nails to glue/seal it.. seems to be holding up fine

I use fiberglass and resin to secure pvc to mdf.

You could use fiberglass resin but a can will cost you as much as a whole aero port

I cut the baffle hole the same ID as the PVC and round it over to create a flare. I cut another piece the same OD as the PVC and glue it to the inside. I do the same for the other end and sandwich the pipe between them, then caulk it. Looks good and holds the pipe secure.

exactly, FG would be my best bet but this project is on the cheap hence the pvc:)

I hear you. I usually use scraps like the baffle cutout to make the inner pieces. You can also use a small piece to glue from the side of the box to the edge of the pipe and use some plumber's strapping to secure it.
