Each part has been thoughtfully separated for the easiest printing. The included Bambu Studio files also include the pieces in the best orientation but also the best weight distribution. Due to the nature of the tank, if you print it in uniform infill it will want to tip backwards. To counter this you'll want to print the front portion in around 60% infill to properly balance it.
Check the link in the 'Materials Needed' doc for a link. You'll want to be extra careful with the magnets as they're quite strong but all it takes is inserting the small magnet into the bottom of the tank and boom - instant actual levitation!
2mm diameter rods are used in miscellaneous parts and I'd recommend picking up a set. They are used down the barrel for reinforcement, as radio antennas on the backside, and on the top hatch as a hinge so it can actually open. We'll be making a line of corresponding droid minis to fit in the hatch as well!
