3D Printing Signal Lamp

Using an D1 Mini (ESP8266) and a LED ring this lamp automatically lits if one of my 3d printers is busy printing. 

Source files: OpenScad file for 3D model and Arduino script for D1 Mini (edit this to fill in the details of your printer(s)).

Filaments used: Polymaker Marble White PLA and Hackerstore PLA Black.
