u"""总装里 EndPlate_v10 → **v12**（多了 A 组 8 + C 组 4 个 Ø4.2×6 螺母孔），并核「螺丝拧得进去」。
|
||
|
||
摆位与 place_v10.py 完全相同（西：不转、外表面 −38.4；东：绕 z 180°、外表面 136.4、dy=2×51.345）。
|
||
|
||
判据：
|
||
1. 两块端板装配 box 与 v10 时一致；
|
||
2. 干涉仍是 360 基线；
|
||
3. ⭐ **同轴核对**：在装配坐标下，把端板上 12 个 R2.1 螺母孔的轴线，
|
||
与南板/北板/顶盖上 Ø3.4 过孔的轴线逐一配对 —— 同方向、横向偏差 < 0.05 才算拧得进去。
|
||
这是「孔打出来了」和「螺丝能穿过去」之间的那一步，包围盒/干涉/直方图都回答不了。
