A sporty open-top two seater in stylish two tone finish.
Update (12/19/11): Added the bottom insert with no landing gear. I find that when giving these as gifts to children, the landing gear legs are the first to break.
Print the top half and bottom half in one color, the top insert and bottom insert in another. (Or heck, print all four parts in different colors).
Glue the top insert into the top half, and the bottom insert into the bottom half. Put little bits of filament into some of the registration holes to keep everything lined up. Glue the halves together.
Print out a couple of little green men (thing:11810), tiny version, and glue them into the cockpit.
