画像を確認しました。以下の問題点があります：

1. **左板の配置が間違っている** - 左板が正しく反対側に配置されていない
2. **knuckle の Y 方向配置が誤っている** - 左板は Y=0,6,12 ではなく、Y=0,12,24 であるべき（外側2個+中央1個の互い違い配置）
3. **右板の knuckle 位置も修正が必要** - Y=6,18 ではなく Y=6,18 で正しいが、全体の配置を見直す必要がある
4. **180° 開いた状態での座標系が不正確** - 左板と右板が同一平面に並ぶよう配置する必要がある
5. **ピン軸の位置** - Y 軸に沿うが、0～32mm の範囲にすべき
