Windmill / Windkraftwerk

With his case you can assemble a simple windmill kit (e.g. from [Aliexpress](https://www.aliexpress.com/item/32882978611.html)) into a nice wind power plant. I used for a school lesson to explain how wind generates electricity.

**Required material:**
- Generator, LED and Windmill: e.g. from [Aliexpress](https://www.aliexpress.com/item/32882978611.html)
- M3x5mm oder M3x6mm Screw: e.g. simple wood screw
- M3x5mm Screw (2 pieces): e.g. [Amazon](https://www.amazon.de/Poppstar-Festplattenschrauben-Festplatten-M3x5mm-silber/dp/B01HBRG3W8) - optional

You can also replace the impeller by this [thing](https://www.thingiverse.com/thing:6129335) to build a water power plant.
