Adafruit Trinket Project Box (Skate Lights)

This is a box that I designed and had 3D printed (SLS Nylon from 3D Hubs) to hold a 9v battery, a switch and a 5v Adafruit Trinket (which can take up to 16v). It was designed to attached to the rear of my daughter's inline skates in order to run a strip of WS2812B RGB LEDs mounted around the boot.

I wrote the code for the Trinket myself but all of the light patterns are derived from this brilliant post
