Anemometer

Anemometer with three blades for fast use: Print and use. You only need a 22mm bearing with a hole large enough to fit a Metric 5 screw and 8mm wide hex nuts. The blades are fixed by the precision of the machine itself, so screws are not needed for attachment. However, glue can be applied if desired. Additionally, there are holes in the legs for attachment with screws between 2.8mm and 3mm in diameter. This model is highly efficient and adapts well to wind speed.
