  "description": "公共工房・学校の金属加工室に据える小型旋盤。二連キャビネット台と切粉皿、主軸台、中心が実開口の三爪チャック、二本のベッド案内面、往復台・横送り台・角形刃物台、心押台とセンター、手輪と外装送りねじを造形。台を含む一式1点で、加工物は付属しません。回転・切削・送り・荷重などの機械動作や安全性能は実装・検証していません。 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）1.420 × 1.254 × 0.662 m、33,108三角形。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 compact lathe for floor placement in public workshops and school metalworking rooms. It includes twin stand cabinets and chip tray, headstock, genuinely open three-jaw chuck, two bed guides, carriage/cross slide/square toolpost, tailstock with center, handwheels and exterior lead screw. The stand and machine count as one assembly; no workpiece is supplied. Rotation, machining, feeds, loads and safety performance are neither implemented nor validated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.420 × 1.254 × 0.662 m; 33,108 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.",
