Humidifier controller case

This is a custom case for a [Spark Core](https://www.spark.io) WiFi microcontroller mounted on a [“perma-proto” breadboard-style PCB](https://www.adafruit.com/products/1608) by [Adafruit](http://www.thingiverse.com/adafruit/about) and a solid state relay. The microcontroller is connected to a temperature/humidity sensor and the relay controls a humidifier based on the measured humidity. The sensor values are also logged to a Google Docs spreadsheet.

The case was modeled in [Autodesk Fusion 360](http://fusion360.autodesk.com/about).
