  "description": "自動車整備店用の汎用タイヤ交換機。中空の固定キャビネット、隙間を持つ四分割ターンテーブルと四つのクランプ爪、後部支柱と旋回アーム、縦軸と脱着ヘッド、三つのフットペダル、側面のビードブレーカーの湾曲パドル、裏面ルーバーと空気調整器を造形。タイヤ、ホイール、車両、外部の圧縮空気源と電源ケーブルは含みません。外観用の静的モデルで、回転・空圧・電気・脱着機能や安全認証はなく、製作・整備・操作・安全の指示を提供しません。 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）1.102 × 1.617 × 0.931 m、22,404三角形。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 generic fixed tire-changing machine for automotive workshops. Features a hollow cabinet, four-sector turntable with open slider gaps and four clamping jaws, rear upright and swing arm, vertical shaft and demount head, three foot pedals, side bead-breaking lever with curved paddle, rear louvers and air regulator. Tire, wheel, vehicle, external compressed-air supply and mains cable are not included. This is static appearance geometry with no rotation, pneumatic, electrical or demounting function or safety certification, and no engineering, maintenance, operation or safety instructions. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.102 × 1.617 × 0.931 m; 22,404 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.",
