A NACA duct intake for foam planes. The cutout needs to be 2.5 inches wide and 3 inches long and have 0.2 inches gap around it for the lip. It has a pretty big opening and 2 of them are enough to cover a 40mm EDFs intake area. They would also be good for cooling an esc with a heat sink or a DJI O3 (those get hot so it might not be enough). I did do some sanding on the one in the pictures to smooth the surface of the intake ramp and to get rid of the strings on the underside of the overhang bit which isn't necessary.
