Aquarium Heater

Titanium aquarium heater 300 mm long: a slim dark grey tube with a black cap end, a moulded suction-cup bracket clipping it to glass, a red status pip on the cap and a black lead trailing from 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
