PORTABLE WIFI RGB 3D PRINTED BIG LETTERS

I've made a few letters with my big printer, two parts, the exterior/back in black PLA and the top/front cover in white PLA as a diffuser. Inside a few strips of WS2812b leds, a batterie, a 5v to 3,3v converter and an esp8266 that allows each letter color to be changed, hell'a'cool letters these are!
