Hi @, here I have a windmill for you.

Version 2
Placed and some textures reduced.

It must be installed with the GE.
The mill has a lot to see. Everything is moving.
The mill head can be turned into the wind, that can be done when standing on the gallery.
The doors can also be opened and closed.
Everything else is independent.
What has to be observed, what has to be entered in the ModDesc and what has to be inserted into the folder Scripts.
Now have fun with the mill.
Greeting PowerPeter008
