Simple anemometer

I needed an anemometer to see when I can fly my RC models. Basically when it turns even very slowly- I wouldn't fly with smaller models.

The last one I printed was from ABS and it lasted 2 years on the sun (35C) and in the cold (-20C) ... Now I'm trying PETG

This design uses a 608 bearing and a 10mm rod for the anemometer itself.
