Firslty, big thanks to adafruit for the original model: https://www.thingiverse.com/thing:1711186

The thing measures 50x30x30mm, is powered by a single CR2032 battery, and has a cool colour changing effect (thanks to a couple of internal LED's)

Here is a video of it working: https://www.youtube.com/watch?v=cQTjZl2dCfk
