  "descriptionEn": "A closed-lid storage bin for grit or de-icing material beside sloping streets and sidewalks. Includes a tapered hollow body, reinforcement ribs, weather-shedding lid, hinges, handles and ground skids. Loose grit and spreading tools are not included. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.250 × 0.857 × 0.828 m; 4,172 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
