Access Stair

Exterior access stair bolt-on, 2m wide and exactly 3m tall to reach one story, astro orange open stringers with gunmetal treads and a slim handrail, flat back face so it butts against a module wall.

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
