Internal Partition Wall

Internal partition wall module on the kit's 1 m grid: 1 m wide, 3 m tall, dead-flat 0.15 m-thick ends on the module edges, joining the exterior wall and itself at every value. one part with opening = solid, door (default solid).

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
