Rocket toy with pull back gearbox

Inspired on the Firebird Mk1 car.

The model needs a pullback geabox, I got mine from another toy :P
If you can't find it, it can be assembled with a tempered steel wire and a couple of printed wheels.

I print it with PLA at 0.34 mm layer and 15% infill, it took about 2 hours.

Have fun with the kids!
