  "description": "旅客ターミナルの搬送ヤードに置く低床の牽引式手荷物トレーラー。四輪・車軸と下部フレーム、木材色の個別床板、側部ガードと前立て、閉じた後扉・蝶番・掛け金、前輪側ボルスターに繋がるA字ドローバーと実開口の牽引環を造形。牽引車・荷物は付属せず、全体で一台です。車輪、操舵、扉、連結は静止し、牽引・荷重や道路適合性の検証はありません。 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）3.140 × 0.892 × 1.539 m、27,716三角形。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 low baggage tow trailer for passenger-terminal handling yards. It has four wheels and axles, underframe, individual wood-colored deck boards, side guards/front headboard, closed rear gate with hinges/latches, and an A-frame drawbar connected to the front steering bolster with an actual open towing eye. Tug and luggage are absent; the entire trailer is one model. Wheels, steering, gate and coupling are static; towing, load and road compliance are not validated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 3.140 × 0.892 × 1.539 m; 27,716 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.",
