# v6：嵌入式 —— 外形 = 顶盖内腔四边各让 0.3，拧紧后顶面压住顶盖角柱底（z −10）、底面与墙底齐平（−13.6）
|
||
# v5：无滤网版 —— 西边缘 −17.9（不再托滤网/导轨），脚垫窝随中心重排
|
||
u"""**底盖 v4**（2026-09-13 外观美化 A + E）。
|
||
|
||
与 v3 的差别：
|
||
A 四边**内缩 0.5**：外形 x −24.3~115.4、y −3.555~106.245（顶盖外沿 −24.8~115.9 / −4.055~106.745），
|
||
接缝处形成一圈 0.5 阴影缝，藏住两件的打印公差；四角圆角用 R2.5（与顶盖 R3 同心）——圆角由 add_fillets 后做。
|
||
E **加厚 2.4 → 3.6**（向下长，底盖顶面仍在 z=−10，机内尺寸不变；整机高 +1.2）：
|
||
· 四角 M3 过孔下方挖**沉头 Ø6.5 深 2.0**，螺丝头不外露，头下还剩 1.6（2.4 厚时只剩 0.4，会压裂）
|
||
· 4 个**脚垫窝 Ø10 深 1.0**（贴 Ø10 硅胶脚垫），放在螺丝内侧、不盖住螺丝 ⇒ 拆盖不用撕脚垫
|
||
PCB 立柱、柱顶螺母孔、四角过孔位置与 v3 相同。
|
||
|
||
本地坐标：板 z −3.6~0、立柱 0~10；装配 dz = −10 ⇒ 板 z −13.6~−10。
|
||
面上切除沿用 NOTES §37：进草图后读 ModelToSketchTransform 验平面，再按变换精确画。
