Saguaro Cactus

A columnar saguaro cactus, a fluted trunk 4 m tall of a dozen vertical ribs rising from a flat base on a 0.6 m footprint, with a knob of 0 to 3 arms that rise from the trunk with a real elbow and then run parallel to it.

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
