Vortex generator

thingiverse

Kindly pardon my inexperience in Blender design, which I've only started learning last week. This created model represents a vortex generator for a car. Strategically placing multiple of these near the rear can decrease drag by approximately a few percent. The provided STL file solely contains the airfoil or wing; I print it with a raft and use double-sided foam tape to attach the raft as the mounting surface. In case of loss during driving, I can easily print another. For optimal results, I scale up the model by 2x when printing.
