Wind Turbine Hub

These 3D print models are wind turbine hubs which can be mounted directly on 2mm project toy motors. The hubs are used to build small scale wind generator projects which are useful for science fairs or STEM classrooms. These hubs are the useful transition between the generator shaft and the model wind turbine. The designer or student just needs to add blades to the hubs using paper, cardboard, Styrofoam, and wood dowels for the blade axels. The designer or student has flexibility to experiment with blade angle, pitch, number of blades, and or material to achieve a high performing wind turbine device.
