  "description": "建物の機械室・配管展示に置く無銘のゲート弁。両端の実開口フランジ、丸い鋳物風胴体、ボンネットと開いたヨーク、外に見えるねじ付き弁棒、四本スポークの手輪、小さな支持脚を造形。外部配管は含まず、接続位置に合わせて配置してください。内部ゲート機構、開閉、流量・圧力性能や配管規格への適合は検証していません。 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）0.495 × 0.845 × 0.340 m、13,308三角形。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 unbranded gate-valve exterior for building plant rooms and pipework displays. It has genuinely open end flanges, rounded cast-style body, bonnet/open yoke, exposed threaded stem, four-spoke handwheel and small support feet. External piping is absent; position it to suit your scene connections. Internal gate mechanics, operation, flow/pressure performance and piping-standard compliance are not validated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.495 × 0.845 × 0.340 m; 13,308 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.",
