This is a 3D model for a mini disco ball. Print it out.
You may also need a gear motor.
Install the 12-lights led and gear motor into the printed base with reference to the diagram;
The exterior is completed;
Connect the reflecting ball to the gear motor using the printed linking components (here I have used hot glue instead), connect to Arduino and then upload the codes (Codes for the LED ring are sample codes from the Adafruit_NeoPixel library).
The ball is flashing like a twinkling star. It’s all done!
