  "description": "交流室・路上演奏の待機場所・音楽室向けの、三脚スタンドで保持した無銘の六弦ギター。曲線の中空胴と実開口のサウンドホール、ネックとヘッド、16本のフレット線、六本の固定弦、ペグ、ブリッジ、下部受けとネック支えを造形。ギターとスタンドで一式1点です。演奏者・ケース・楽譜は付属せず、弦振動・音声・調律・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）0.480 × 1.123 × 0.385 m、17,668三角形。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 six-string acoustic guitar held on a tripod stand for community rooms, busking rest areas and music rooms. A curved hollow body and actual sound-hole opening accompany neck/headstock, 16 fret wires, six fixed strings, tuning keys, bridge, lower cradle and neck support. Guitar and stand count as one assembly. Player, case and sheet music are absent; string motion, audio, tuning and real acoustic performance are unvalidated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.480 × 1.123 × 0.385 m; 17,668 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.",
