Bottle Cap

Bottle cap, 3.2m across, a dish or tub for bugs: a crimped steel crown cap with 21 flutes round the skirt, a flat top in one plain unprinted colour, and a cork-coloured liner modelled inside so it reads face-up or face-down.

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
