OpenSCAD設計的3D打印NodeMCU外殼

    NodeMCU是集成了WiFI和MCU的小巧開發板，基於ESP8266芯片。論壇在http://bbs.nodemcu.com/，源碼在https://github.com/nodemcu。

    使用OpenSCAD給它作了一個外殼，能夠用3D打印機輸出出來，就不再用「裸奔」了。

OpenSCAD的原始模型文件以下，能夠自行修改後在3D打印機上輸出。

//打印時注意比例變化，而且旋轉向上。
//避免上部打印時無支撐塌陷。
//蓋子單獨打印，或放爲兩個模型。

//常量定義
athick=0.5;	//蓋子厚度
bthick=0.10;	//盒壁厚度
bwidth=4.0;	//內徑淨寬
bhight=1.5;	//內徑淨高

blong_inter=5.5;//內徑淨長
//外徑長度＝底厚＋內徑＋擋格＋蓋子厚度
blong=bthick+blong_inter+bthick+athick;
