It's a simple wind turine with rotatable blades. Made in Blender with two versions available:

Raw - as it was modelled, modifiers are not applied, you can adjust or remove them as you wish (you can still rotate the blades since they are are a separate object). Final - all modifiers applied, UV mapped, textured, rigged (Rotation can be controlled with bones).

The package also includes FBX and OBJ files and an archive with textures. The wireframe previews are from the final version. Image and video previews rendered in Unity. I am not sure if it qualifies as low-poly or not, but Unity seems to be handling it pretty well, even on a potatoe.
