This is from an old old cartoon show called Spiral Zone. It is the Rimfire cannon. There was a tonka version made, but it didn't really do the vehicle justice. There was a bandai prototype as well, but it was never released. I built this in homage to that little known cartoon show. You will need to print 4x tailpipes 2x handlebars and one of everything else. You will need to print the following with supports body.stl cockpit.stl Refer to the exploded view to see how to put everything together. The wheels were designed to turn, though that might require a bit of sanding to get them free. Mine turns, but not freely. I could probably do a bit of work on this to improve it. Glue together everything but the wheels.
