I wanted a decorative VAWT for the garden that will spin in the wind! I like this model, but removed the center part as it is not needed for decorative use. Will easily spin on a small metal or wooden stake (e.g., tent peg, chopstick).
I printed with 0.6 nozzle and 0.4 layer height, but it doesn't really matter. Just make sure you print with supports (highly recommend tree/organic supports). Print with two perimeters and 0% infill to keep the weight down.
The author remixed this model.
