3D model description

This is simply plugged into your mobilephone earphone jack, and together with the App from Vaavud you can measure windspeed.

What you need is a old 3,5mm earphone connector, a 8x5mm ballbearing, and 2 strong magnets (rear earth) 6x2mm
Assembly is easy, no electrical connections, the head phone connector is only for rigid placing of the fan.
