Build Circle PCB for 2 LEDs

Please engineer, design, build a PCB board containing 2 quantity of 12 volt Red Green Blue Light Emitting Diodes (RGB LED) Please make PCB a circle, with a diameter no larger than 21mm. Please make the board capable of being controlled using WS2812 protocol from Data input. Please make the board capable of receiving 36 volt input from metal connections for (1) Ground, (2) Data, (3) Positive (36v) Please have identical output metal connections for (1) Ground, (2) Data, (3) Positive (36v) on the opposite side of the circle as the input metal connections. Please add additional electrical components as needed to provide functionality for reducing 36 volt input to 12 volt LEDs. Please advise if anything additional is needed to accomplish the task of creating the PCB
