Cut-open drum planter

Single oil drum cut open lengthwise into a herb planter, about 0.9m long, riveted rusty steel with mint and cream paint flaking off, dark soil inside and a knob taking it from bare soil to a full spilling bush of herbs, small timber feet under 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
