Openscad Design 3D Print NODEMCU housing

The NODEMCU is a compact development board with integrated WiFi and MCU, based on the ESP8266 chip. Forum in http://bbs.nodemcu.com/, source code in HTTPS://GITHUB.COM/NODEMCU.

Using the Openscad to make a shell, you can use the 3D printer output, and no longer "bare-Ben".

OPENSCAD's original model file is as follows, which can be modified and output on the 3D printer itself.
