+# 交给打印店：编码器支架与垫片一盘打印
+
+请使用同目录的单个 STL，按原尺寸和摆放方向一次打印。成品包括：
+
+- 半开放立柱编码器支架 1 个；
+- 厚 **0.5 mm** 的开口垫片 8 个；
+- 厚 **1.0 mm** 的开口垫片 8 个。
+
+这是一个包含 17 个互不相连零件的 STL，零件已排好，不需要逐件导入或重新排版。支架面板贴打印平台，立柱向上；垫片平放。模型范围约 **91.6 × 134 mm**，附着边、裙边和清洁线需另留空间。不要缩放或改变模型比例。
+
+## 切片建议
+
+1. 使用 PETG 和打印机已有的 PETG 配置；层高和首层高度均建议 **0.1 mm**。在切片预览确认 0.5 mm 垫片为 5 层、1.0 mm 垫片为 10 层，且厚度没有被切片软件取整改变。
+2. 采用**逐层打印整盘**，确认四个半开放立柱、贯穿孔、垫片缺口均正常；按切片预览判断是否需要支撑。
+3. 支架建议至少 3 道外墙。垫片如附着不稳，可尝试约 3 mm brim；请在预览中检查相邻零件的 brim 未连接，且没有超出有效打印范围。
+4. 打印冷却后清除 brim、毛刺。检查支架 1 个、垫片共 16 个，并按厚度分开装袋标记。
+
+## 两组垫片不能混淆
+
+预排版为左侧 0.5 mm 组、右侧 1.0 mm 组，每组各 2 列 × 4 行。请以实际切片后的排版方向为准：在模型高度 0.6 mm 的切片预览中，只有 1.0 mm 垫片组仍有打印路径，0.5 mm 垫片已结束；支架仍会继续打印。打印后保持盘面相对方位，冷却后**先按预览取一组、装袋并标注厚度，再取另一组**。预览图中的不同颜色只是标记厚度，使用同一种颜色和材料打印即可，无需双色打印。
+
+初次装配时通常在每根柱下放一片 0.5 mm 垫片，四处厚度相同；装配时将每片的开口旋转对准对应立柱的开口及相邻角码。1 mm 垫片和多出的 0.5 mm 垫片用于备份或调整，可以根据实测间隙选择是否叠加，不需要全部叠在一起。增减厚度会改变磁铁间隙和螺丝进牙，需根据实际设备核对。
+
+此文件是 STL，尚未针对具体打印机生成 G-code，也未进行实物打印。原支架和垫片的几何没有改变；电机孔位、螺丝和实际磁铁间隙仍需试装确认。
