  "description": "交流ラウンジや小規模舞台向けの五胴ドラムセット。バスドラム、二つのラックタム、フロアタム、スネア、三か所のシンバル台（ハイハットは上下二枚）、ペダル、椅子と置いた二本のスティックを一式で造形。各ヘッド、金属輪、張力金具、支柱・三脚・ゴム足に実形状を持たせています。全部を1点と数え、演奏者・音声・振動・ペダル動作・調律は含まず、演奏性能は未検証です。 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）1.662 × 1.035 × 1.200 m、42,676三角形。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 five-drum set for community lounges and small stages: bass drum, two rack toms, floor tom and snare, with three cymbal-stand positions (two cymbals at the hi-hat), pedals, stool and two parked sticks. Heads, metal hoops, tension fittings, poles, tripods and rubber feet are modeled. The complete set counts once. Player, audio, vibration, pedal behavior and tuning are absent; performance as a real instrument is unvalidated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.662 × 1.035 × 1.200 m; 42,676 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.",
