+# 当前装配：编码器铜柱版
+
+- `Assembly.FCStd` 为当前装配；`Assembly.step` 为可见零件的 STEP 导出；两张 PNG 分别为总装和电机背面局部。
+- 真实打印板 `models/encoder_standoff_plate_print/EncoderPlate.FCStd` 已装进总装，位于电机背面上方 11 mm；四根铜柱柱身长 10 mm、对边 7 mm，每柱上方各一片 1 mm 示意金属垫片。M4 公牙长度按 5 mm 示意，顶部螺丝长度同样示意，并非采购建议；电机孔深及铜柱母牙深度仍需按实物确认。
+- 保留 12 个 20 × 20 × 16 × 1.8 mm 小角码与 6 个长孔角码。电机四个角码贴紧电机，各角码与 2020 之间示意垫片总厚 2 mm。型材采用已订购规格：3030 型材 250 mm 两根、70 mm 两根；2020 型材 140 mm 两根、130 mm 一根。
+- 风扇外框和灯光开关包络为示意，灯光开关的实际固定由用户自行处理。轴套和拨片是概念件，不作为打印定稿。
+- PCB、芯片和三个 PCB 螺丝头已随实际板相对旧版一起移动 0.1 mm，PCB 与支架模型贴合且无实体相交。芯片到磁铁几何最短距离约 1.1 mm，但 PCB 厚度、芯片高度与磁铁座尺寸均为假设，非实测数据。
+- 依据当前简化几何，四个铜柱离电机固定小角码最小距离约 1.16 mm；新增支架、铜柱、垫片、示意螺丝与非配合的可见零件无正体积相交。局部螺纹配合、角码实际弯曲、线束、工具、风扇轮毂与实际加工误差并未验证。
+- `验证.json` 为数量、几何间隙和检查范围，FCStd 重开及 STEP 载入有效；不能代替实物试装或结构强度测试。
