  "description": "木工・模型工房で平材の面や端部を研磨する一体型据置機。共通のキャビネット台・駆動部に、上下ローラーを巡る厚みのある連続ベルト、支持プレート、円形の平面研磨ディスク、別々の材料受け、ガード、調整つまみと二つの開口集塵口を組み合わせています。刃物研ぎ用の両頭グラインダーではなく、一式を1点として数えます。材料は付属せず、回転・研磨・集塵・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）0.781 × 1.520 × 0.683 m、19,072三角形。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": "One stationary assembly for finishing flat-stock surfaces and edges in woodworking and model-making workshops. A shared cabinet and drive carry a thick continuous belt around upper/lower rollers, backing platen, flat abrasive disc, separate work rests, guards, fixed adjustment knobs and two open dust outlets. It is a stock-finishing belt/disc machine, not a double-wheel sharpening grinder, and counts as one assembly. Stock is absent; rotation, sanding, extraction 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): 0.781 × 1.520 × 0.683 m; 19,072 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.",
