The system consists of several parts. You may or may not need all of them. 

The plate attaches to the printer using the rubber feet that hold the printer up. Since this alters the height of the back feet, there are spacers to match the front feet to the same height. 

The tube adapters (you need 2) slot into the back of the plate, over top of the Mars 2 Pro's vents. I glued mine in place. 

I used some hose I had on hand to connect the tube adapters to a random PC fan I had, which I then also put an outlet adapter on so it would fit a PVC vent I have through the wall. This is probably not the most efficient air moving system, but it serves its purpose for my use.
