Vertical Wind Turbine

Now updated with MK3.1 - Which allows you to generate power!

A vertical turbine design which will turn freely in the wind, or when printing Base_Motor, you can use it in conjunction with a motor to generate power.

The motor used in my design is a 28mm diameter printer motor. If you decide to use a smaller motor, you could possibly print a spacer of some sort. You will also need to print the Arms_Gear and Motor Gear files, or if you wish to run a pulley system instead, then print the Arms_Pulley and Motor_Pulley files and find yourself an elastic band!

The Arms_Gear / Arms_Pulley files can be attached to the arms with 2 - 4x 25mm or longer M4 bolts

The turbine can be built in layers - I built a two layer version, as per the image.

The arms are printed in sets (Arms_Top & Arms_Bottom combine to make one set)
For a single tier turbine you need 2 sets, for a double tier turbine you need 3 sets, etc.

The design uses standard skateboard bearings and a length of 8mm threade
