OLED Display and Desk Decoration Cube/ Arduino Nano & neopixel & SSD1306

Got my inspiration for this from this reddit post

A simple box for and SDD1306 OLED display, hooked up to an Arduino nano, with one WS2812 color LED (neoPixel).

The cover on the back simply slides in, no screws or glue needed!

The code that I uploaded, shows a simple animation and slowly changes the color gradually along the rainbow by random (walk).
I simply modified the sketch I found here.

I designed the box in OnShape. Source Files
It is quite a tight fit, i had to push a little, but holds well!
