  "description": "食品売場や厨房の作業台に置くチャンバー式真空包装機の外観。深さのある空の槽と前方シールバー、上げた金属蓋の内張り/ガスケット、ヒンジと固定ステー、無表示操作面、背面通気と接続部を備えています。袋や食品は含まず、蓋は不透明な金属表現です。台の高さに合わせて配置する静的モデルで、減圧・加熱シール・蓋の動作や圧力容器の性能は実装・検証していません。 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）0.492 × 0.747 × 0.719 m、6,904三角形。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 chamber vacuum-packaging machine exterior for food-shop and kitchen worktops. It has a genuinely recessed empty chamber, front seal bar, raised metal lid with inner liner/gasket, hinges and fixed stay, blank controls, rear vents and connection exterior. Bags and food are omitted; the lid is opaque metal. Position at worktop height. Vacuum, heat sealing, lid movement and pressure-vessel performance are neither implemented nor validated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.492 × 0.747 × 0.719 m; 6,904 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.",
