I see no reason to test the aerodynamics of a model car.

It might be of some use to those of us who also race slot cars and need help getting body choice and mounting angle and position suitable for a specific track.

Not to mention what it could do for the Pinewood Derby .

Maybe just for fun?

Or maybe, if somebody is interested in science and engineering, to get a visual idea of the difference in airflow over a barn-door design like a '32 Ford as opposed to a late model Lambo?

Granted data developed in 1/24 - 1/25 scale doesn't translate to full size, but turbulence around chunky objects can be visualized and perhaps better understood.

What I don't understand is the need to 3D print any of it. The side walls are flat, and cheap high-flow fans in their own housings are plentiful.

That is actually a valid idea. Eons ago at the dawn of time, I discovered that air can get under the bodywork of a slot car and lift it, making it leave the track...just exactly as years later I saw Mark Donohue fly the Can Am Porsche at Road Atlanta

Wind tunnel testing has always involved the use of models, actually, only a bit larger.
