prompt

OpenSCAD で、向きが指定されたマグカップを作ってください。

本体:
- 外径 80mm、内径 70mm(肉厚 5mm)、高さ 90mm の円筒形マグ
- 底面の厚みは 6mm
- 内側は飲み物を入れられるよう中空

取手(handle):
- マグの **+X 軸方向の側面のみ** に付ける(他の方向には付けない)
- 取手は D 字形状(外側が半円、本体側が直線)で、本体外周にしっかり接続する
- 取手の内側の空間は高さ 30mm × 幅 25mm(指 3 本ぐらい入る)
- 取手はマグの高さ方向の中央付近に付ける
- 本体と取手は確実に union され、マニフォールド(隙間や宙吊りなし)を保つ
