The 3 pieces as well as 2 different styles of MMU print gcode are included. One is the staggered edge as I've printed and one is a more simple 2 color bottom block. For mine I used Amolen glow in the dark PLA for the top, Esun PLA+ for the brown parts and Prusament PLA for the green.
You will need to print the bulb base and the torch top with supports, the torch body doesn't need any.
