prompt

OpenSCAD で、L 字に折れた金具(L-bracket)を作ってください。

形状:
- 水平面と垂直面の 2 つのフランジが直角に繋がっている
- 水平面は 50mm × 40mm(幅 × 奥行き)
- 垂直面は 50mm × 40mm(幅 × 高さ)
- 板厚はどちらも 3mm
- 内側コーナーが原点になるように配置(水平面は +Y 方向、垂直面は +Z 方向に伸びる)

皿穴(countersunk holes):
- 各面に 2 個ずつ、合計 4 個
- M4 ねじ用(貫通穴 Φ4.5mm + 皿座面 Φ8mm × 深さ 2mm)
- 各面の中心線上で、面の縁から 10mm 内側、左右対称に 2 個並べる
- 皿座面は外側(ボルト頭が当たる側)に向ける

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。
