  "description": "学校の音楽室や交流施設向けの架台付き木琴。長さを変えた20枚の木色バー、保持ボタンと支持コード、下側が開いた20本の共鳴管、台枠・支柱・四個の車輪、横のマレット置場と二本のばちを造形。バー・管・ばちを含む一式1点で、音域・調律された周波数を示す設計ではありません。音声、振動、可動機構や実楽器の音響性能は未検証です。 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）1.265 × 0.896 × 0.562 m、20,468三角形。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 educational xylophone prop on a wheeled frame for school music rooms and community facilities. It has 20 graduated wood-colored bars, retaining buttons/support cords, 20 bottom-open resonator tubes, frame/uprights/four wheels and a side tray with two mallets. Bars, tubes and mallets count within one assembly. No particular musical range or tuned frequencies are represented as an engineering claim. Audio, vibration, moving mechanisms and real acoustic performance are unvalidated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.265 × 0.896 × 0.562 m; 20,468 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.",
