Rolled plate silo

4x4m footprint grain silo, a tall swelling cylinder of rolled salvage plate with oversized rivet rows and a shallow copper cone cap topped by a small brass vent, 9m tall at exactly 3 floors of 3m, a hopper chute and hatch at the base.

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
