  "description": "金属加工場の背景に置く手動3本ロール曲げ機。四脚と補強、左右の軸受フレーム、三本の離れたローラー/主軸、片側の歯車外形、反対側の三本スポーク手回し輪と握り、二つの上側調整ねじ/つまみ、固定解除ラッチ外形を造形。板材や加工結果は付属せず一式1点。ローラー回転・歯車伝達・曲げ精度・荷重や安全性能は実装/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）1.508 × 1.435 × 0.582 m、11,324三角形。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 manual three-roll machine for metalworking backgrounds. It has a braced four-leg stand, side bearing frames, three separated rollers/shafts, visible gear exteriors on one side, a three-spoke handwheel/grip on the other, two upper adjustment screws/knobs and a fixed release-latch exterior. The whole assembly counts once; no stock or finished sheet is supplied. Roller/gear motion, forming accuracy, load and safety performance are unimplemented and untested. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.508 × 1.435 × 0.582 m; 11,324 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.",
