Recessed Floor Box

Small recessed floor service box set into an access floor tile, 0.3x0.2m, with a lid knob (closed flush brushed lid, open showing sockets and data ports, open with a power lead running out).

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
