+u"""在已开着的 EndPlate_v12（已倒角、12 个螺母孔已验）上补 **L 脚 2 个 Ø3.4 锁孔**，另存 v13。
+
+配方与 C 组相同（已验证可行）：z 常量面（脚顶面 z=2.4，朝外 +z）上建草图，uv = 模型 xy，沿 z 切。
+孔位：本地 x=36.5（装配 −1.9，对托盘原锁孔）、y=21.345 / 81.345，切深 2.6（脚厚 2.4，切穿）。
+
+判据（双向）：R1.7 由 4（风扇孔）→ **6**，且新增的 2 个轴沿 z、位于 x 36.5 / y 21.345、81.345；
+R2.1 仍 6、R3.0 仍 4、R30 仍 1。
