Anemometer Wind Speed Indicator

A simple 3D-printed anemometer designed for visual wind indication. The rotor spins freely in the wind, providing a clear and engaging demonstration of airflow and wind direction, but it does not measure or display actual wind speed. Ideal for educational projects, decoration, or basic outdoor experiments. The assembly requires one M3x15 or M3x20 countersunk screw and a threaded insert M3.
