Cup Anemometer / wind meter for outdoor use

With this small model of a anemometer you can observe the wind speed or count the revolutions of the cups in a minute. It is also a nice model for experiments or explanations or you can check if it is windy outside,

The axis, connector and cups have a thread to screw the parts together. I have glued the parts to give the model more stability.

You need support material for the axis and the connector.

I have designed the parts with Fusion 360 and used the Prusa slicer.
