Oil-drum wind spinner

Village wind spinner about 6m tall, split oil drums curved into a vertical rotor turning on a slim bolted lattice mast with a brass bearing housing and a small gauge at its base, flaking rust orange and mint drum halves, rotor as an animatable group.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
