u"""派生 topshell_v8 / place_v8 / render_v8（2026-09-13 用户：格栅无法打印 → 方案 A「竖槽 + 3 条横撑」）。
|
||||
|
||||
问题：倒扣打印时端墙竖着长高，竖槽之间的筋 1.2 宽 × 2.4 厚 × 最长 64 高（长细比 > 50），
|
||||
只有下端连着墙往上悬空长 ⇒ 晃动、拉丝、打断。
|
||||
改法：在风扇中心 z −16 / 0 / +16 加 3 条 1.2 宽的水平横撑，每条竖槽被切成若干段，
|
||||
最长悬空筋段 64 → 16；开孔 2295 → 2138 mm²（原 Ø60 的 81.2% → 75.6%）。
|
||||
每段轮廓：挨着槽头的一端保持半圆，挨着横撑的一端是平边；横撑必须整条落在槽的直边段里或完全不碰槽（断言）。
