Mine is the same as Tom's only I made it myself and cut the bottom out to let the motor stick down a couple of inches to breathe clean air and be able to raise and lower the router lift. It could also be used on the lift out plate method also as long as enough power cord was left in the box, or below, to lift the motor up and set it on the top. I put a hinged door in the front of the box, this could be used to open to adjust the router height and lock the motor if you didn't have a lift.
I can say that it works very well to collect the dust.
I also put an adjustable vent in the side of the box to adjust the makeup air for the DC.
