  "description": "体育室・地域トレーニング室に置く、二つの吊り輪と自立支持フレームの一式。木色の環、上梁から環へ繋がる閉じた平ベルト、固定バックルと折り返し、金属横棒、二本の支柱、前後の斜材、長い接地脚と後部連結材を造形。輪・ベルト・架台を合わせて1点です。吊り輪の揺動・長さ調整・体操動作はなく、耐荷重や運動安全性は未検証です。 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）2.418 × 3.178 × 1.862 m、10,136三角形。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 two-ring support-frame assembly for gymnasiums and community training rooms. It has wooden-colored rings, continuous flat straps linking the top beam to ring crowns, fixed buckles and tails, metal crossbar, twin uprights, front/rear diagonal braces, long floor runners and a rear tie. Rings, straps and frame count as one model. Ring swing, strap adjustment and gymnastic behavior are absent; load capacity and exercise safety are unvalidated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 2.418 × 3.178 × 1.862 m; 10,136 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.",
