Wind turbine for nema 17 stepper motor

thingiverse

Here is a good use for a stepper motor that would otherwise sit around and collect dust. This is a work in progress and the results so far look promising. I wanted a design that was simple and that didn't require any hardware. No screws or bearings needed! The cone threads onto the hub and clamps down tightly on the blades. I am also planning to make a mount and swivel for the motor when I get time and add it on here. I designed the blades to print individually from the hub and print standing vertically, which requires a build height of 340mm. See pic for suggested build plate setup. The cone needs support.
