# CYD 温湿度仪表盘 3D 外壳
|
||||
|
||||
桌面斜立分体外壳，适配 **ESP32-2432S028R（CYD）** + **DHT11（CN1 / GPIO22）**。
|
||||
桌面斜立分体外壳，适配 **ESP32-2432S028R（CYD）** + **DHT11**。
|
||||
|
||||
## 设计要点（当前）
|
||||
|
||||
- **DHT11 在后盖外侧**：卡位槽 + 左右卡舌 + 前端止挡，模块从背面按入
|
||||
- **传感器微突出**约 **1.8 mm**（通风口/探头露出后盖平面）
|
||||
- **前后盖合盖**：前框公止口落入后盖母槽；可用 `4×M3×10` 辅助固定
|
||||
- USB 侧孔、BOOT/RST 开孔、桌面支脚
|
||||
|
||||
## 浏览器预览
|
||||

不要直接双击 HTML（`file://` 无法加载 STL）。在项目根目录执行：
|
||||
|
||||
```bash
|
||||
python -m http.server 8765 --directory cad
|
||||
```
|
||||
|
||||

## 设计要点
|
||||
|
||||
- PCB 基准：`86 × 50 × 1.6` mm，四角安装孔
|
||||
- 前框可视窗约 `59.5 × 45` mm
|
||||
- 后盖背面净空约 7 mm；Micro-USB / USB-C 合并开孔
|
||||
- BOOT / RST 背面开孔；底部散热缝
|
||||
- **DHT11 独立通风仓**（后盖长边外侧），减少板温干扰；线槽通向 CN1
|
||||
- 固定：`4 × M3×10` 自攻进后盖塑料柱（孔径约 2.5 mm）

|
||||
| 参数 | 建议 |
|
||||
|------|------|
|

| 材料 | PLA 或 PETG |
|
||||
| 层高 | 0.2 mm |
|
||||
| 喷嘴 | 0.4 mm |
|
||||
| 墙厚 | 2–3 圈 |
|
||||
| 填充 | 15–20% |
|
||||
| 支撑 | **不需要**（按 STL 默认朝向） |
|
||||
| 前框 | 屏窗朝上打印 |
|
||||
| 后盖 | 底板朝下，支脚伸出床外方向按切片预览摆放 |

## 重新导出 STL
|
||||
## 重新导出
|
||||
|
||||
```bash
|
||||
pip install trimesh manifold3d numpy
|
||||
python cad/generate_stl.py
|
||||
```
|
||||
|
||||
或用 OpenSCAD：
|
||||
## 打印
|
||||
|
||||
```bash
|
||||
openscad -o cad/export/front.stl -D part=\"front\" cad/cyd_climate_case.scad
|
||||
openscad -o cad/export/back.stl -D part=\"back\" cad/cyd_climate_case.scad
|
||||
```
|
||||
|
||||
改尺寸：编辑 `cyd_climate_case.scad` / `generate_stl.py` 顶部参数后重新导出。
|
||||
PLA/PETG，0.2 mm，墙 2–3 圈，填充 15–20%，一般无需支撑。
|
||||
后盖建议 **外底朝下**（DHT 仓朝上或按切片预览，必要时对 DHT 卡舌加少量支撑）。
|
||||
|
||||
## 装配
|
||||
|
||||
1. DHT11 放入后盖通风仓，杜邦线经线槽接到 **CN1**（`3V3 / IO22 / GND`，按你现有接线）
|
||||
2. CYD 屏朝前框放入，USB 对齐侧孔
|
||||
3. 合上后盖，四角 M3×10 拧紧（勿过紧防裂）
|
||||
4. 桌面斜立放置；点屏可调背光
|
||||
|
||||
若孔位与你的板子有 ±1 mm 偏差，优先改 `generate_stl.py` 里 `USB_Y` / `MH_INSET` 后重导。
|
||||
1. 将 DHT11 模块从 **后盖背面** 按入卡位，探头朝外微突出；线经仓内小孔接到 CN1（GPIO22）
|
||||
2. CYD 放入后盖腔体，USB 对齐
|
||||
3. 前框止口对准后盖槽 **合盖**，四角螺丝固定
|
||||
4. 桌面斜立使用
