OpenSCAD で、家具用の小型バット蝶番(butt hinge)を作ってください。
3 つのパーツ(左板、右板、ピン軸)が組み合わさって動作する完成品を、
「開いた状態(180°)」で 1 つの SCAD ファイルに配置して出力します。

寸法と配置:
- 板(leaf)2 枚: 30mm × 25mm × 厚さ 2mm の鉄板形状
  - 縦 30mm の辺がピン軸に沿う(ヒンジ軸方向)
  - 横 25mm の辺が回転で開く方向に伸びる
- ピン軸: 直径 4mm の円柱、長さ 32mm(両端 1mm ずつ knuckle から飛び出す)
- knuckle(筒部): 縦 30mm を 5 等分(各 6mm)に区切り、左板に 3 個・右板に 2 個を
  互い違いに配置(左板は外側 2 個 + 中央 1 個、右板は中間 2 個)
- knuckle 外径 8mm、内径はピン軸 + 0.3mm クリアランス(= 4.6mm 穴)
- 左板と右板はピン軸を共有して回転可能。180° 開いた状態で、両板の
  平らな面が同一平面に来るように配置する
- 各板の knuckle から離れた側に、M3 用の皿穴を 3 個ずつ
  (穴ピッチは板の縦方向に 8mm 間隔、皿穴は表面から見て直径 6mm × 深さ 1mm
  のテーパ + 直径 3.2mm の貫通穴)

座標系:
- ピン軸の中心線を Y 軸に重ねる(ピン軸は +Y 方向)
- 板の平らな面は Z 軸に直交し、左板が x<0 側、右板が x>0 側に伸びる(180° 開)
- knuckle は X=0 を中心とし、Y 方向に 6mm ずつ並ぶ

完成したコード全体を ```openscad ... ``` のフェンスで囲んで出力してください。
コードのみで、追加の説明は不要です。
