  "description": "公共菜園や住宅庭で使う密閉ドラム式コンポスターの外観モデル。八角形ドラム、架台、支持軸、閉じた投入扉、通気カバーと手回しクランクを備えます。中身・内部撹拌羽根・分解処理・回転動作は含みません。 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）1.135 × 1.144 × 0.800 m、6,088三角形。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": "An exterior model of a closed drum composter for community gardens and residential yards, with an octagonal drum, stand, axle supports, shut loading hatch, covered vents and hand crank. Contents, internal paddles, decomposition and rotation behavior are not included. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.135 × 1.144 × 0.800 m; 6,088 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.",
