  "description": "建物の給水設備や実習用配管展示に置く水量計外装。青銅色の胴体、両端の実開口接続、取付脚、丸い無数字の指示面と固定針、開いた保護蓋・蝶番を造形。24本の目盛は装飾で、読み値や校正を表しません。外部配管、測定機構、流れの再現や計量性能は含みません。 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）0.548 × 0.485 × 0.293 m、12,064三角形。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 water-meter exterior for building water services and teaching pipework displays. It has a bronze-colored chamber, genuinely open end connections, feet, round unnumbered face with fixed pointer, and open protective lid/hinge. Twenty-four tick marks are decorative rather than a reading or calibration. External piping, measurement mechanisms, simulated flow and metering performance are absent. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.548 × 0.485 × 0.293 m; 12,064 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.",
