CO2 Pickup Truck

This is a fully 3D-Printable "body-on-frame" pickup truck that rolls like any other toy car. There are no bearings, screws, nuts, washers, or any other metal "helpers" involved. It prints entirely without supports (if you have your print settings dialed in), and it assembles by friction fit. You can glue it together if you like, but it is not required. It is intended to be a CO2 powered rocket car, but I have not yet figured out how to open a 12-gram CO2 canister while it sits in the bed of the truck. I use electrical tape to hold the tailgate on and ensure that the cartridge does not "go rogue" during tests; this is what you can see in the pictures. If anyone prints this and figures out a better solution to launching this than free-handing it with a Dremel cut-off wheel, let me know. Nonetheless, it is a pretty nice toy car, even if I can't blast it down the street with compressed air just yet. It rolls down inclines fairly straight when assembled properly, and it crashes nicely
