  "description": "学校・公共施設の実習室で机上に配置する双眼式顕微鏡。C字支持アーム、実開口のあるステージと標本クリップ、三本の対物レンズ外装、斜めの接眼部、粗微動ノブ、コンデンサー・照明部外形、背面接続口を造形。標本やスライドは含まず、レンズは不透明な色付きPBR面です。拡大光学、照明、焦点調整や検査機能は実装していません。 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）0.220 × 0.509 × 0.292 m、11,364三角形。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 binocular microscope for desk placement in school and public-facility teaching labs. It includes a C-shaped support, stage with a real opening and specimen clips, three objective exteriors, inclined eyepieces, coarse/fine focus knobs, condenser/illuminator exteriors and rear connection detail. Specimen and slides are absent; lenses are opaque colored PBR surfaces. Optical magnification, illumination, focusing and inspection functions are not implemented. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.220 × 0.509 × 0.292 m; 11,364 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.",
