So after watching a video on how to clean your dryer air vent I went in search of an attachment for the end of my air compressor. A reverse airflow attachment that connects to the end of your air compressor hose. You push it into your dryer vent from the outside, turn on the air, and as you pull the hose out it breaks loose the lint and dust that has accumulated.

The only places that seem to have them are professional duct cleaning suppliers. They of course want to sell you a complete duct cleaning system for several thousand dollars, but I figured I could do it for much less. I found an aluminum version for a much bigger compressor than I have and a nylon version. Those gave me an idea on what I wanted to do, and my pictures are of the first version using a drill and a foosball. I also made a video using that foosball skipball.

It was one of my first projects as soon as I had access to a 3d printer and started designing things in TinkerCAD.

Here is a link to the Instructables page in case anyone is interested.
