Pencil Mini VAWT
thingiverse
I decided to build several of these mini turbines to test several characteristics of these Vertical Axis Wind Turbines. In addition to the mini turbine you only need a pencil or a pen. Insert it through the hole and place the turbine perpendicular to an air source strong enough (for example a fan) that makes it spin. The stronger the air the faster it will spin. Printing: The higher resolution the better will be the aerodynamics of the turbine and the better it will spin. The less infill used the lighter and easier to spin.
