The V-Twin RDA was my first production CAD design. Released when I was 18, it was by far the most motivating experience of my life. To have something go from an idea, to renders on a computer, to an actual product was unbelievable. The design was unlike anything else that was on the market at the time, and created a really unique way to handle a 2 coil setup with bottom and adjustable airflow. The flavor was unreal.
These show two different views of the computer designs. The top one shows the unique coil placement.
Below are a couple pictures of the real product. There were three different colors, and there are various pictures of builds.
