I made this 3d printable rocket using Oneshape! To fly it you need a D9 rocket motor with at least 5 secs delay. This rocket uses tumble recovery to land and has no parachute.(yet) The payload bay is intended to carry a Pi-Zero with a LiPO and a camera  but it can also carry other stuff. THIS ROCKET WILL NOT FLY STRAIGHT WITHOUT A PAYLOAD! Always check the center of mass before launching!

Printing: Use only 2 walls and 5% infill with PLA+ or anything lighter, try to minimise the weight of the parts(optimum is below 115g)

IMPORTANT: YOU MAY NEED TO UPSCALE SOME PARTS BY 10x! (Depends on your software)
