Remix of Ender 3 Octoprint Set Up with Power and Light Remote Control

I remixed the original design found at https://www.thingiverse.com/thing:3063845, replacing the base with two high-voltage relays recommended in the original source: https://www.aliexpress.com/item/30A-5V-1-Channel-Relay-Module-Board-With-Optocoupler-H-L-Level-Triger/32814917488.html. Two relays are sufficient, one for power and another for 24V LED lights. The original design featured a relay for both power and ground; I simply blocked the 5-volt pin on the USB cable connected to the RPI board, preventing it from drawing power from the PI.
