This is a small centrifugal fan with a straight-vane impeller that uses a standard 3-6v DC Motor, with basic dimensions provided in the CAD file. This can be used as a cooling fan for a PC, or it can be used for other purposes with the included nozzle. Model is intended to be resin printed, but FDM is fine as well.
