Windmill Pump

Water-pumping windmill on a four-legged braced steel-and-timber tower, a 2.5x2.5 m footprint standing 6 m to the hub, with a vane knob of 12, 18 and 24 flat sheet blades set in a faceted fan wheel rigged to turn on its own axis.

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
