  "description": "改修工事の外壁に配置する短い瓦礫排出シュート。三段の重なり合う中空筒、開いた上部ホッパー、吊り金具と実形状の鎖、壁側取付フレームをまとめた一組です。建物・受け容器・瓦礫や落下動作は含まず、取付高さ・壁離れをシーンで調整してください。耐荷重・粉じん・落下物や施工安全を検証した実用品ではありません。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）0.972 × 2.305 × 0.972 m、24,432三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A short debris-chute assembly for renovation facades, combining three overlapping hollow tapered sections, an open receiving hopper, suspension eyes, modeled chain links and wall-side support frame. Building, receiving bin, debris and falling behavior are absent; adjust installation height and wall offset in the scene. This is not real equipment validated for loads, dust, falling objects or construction safety. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.972 × 2.305 × 0.972 m; 24,432 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.",
