Minirocket for exploding caps

I started learning Fusion 360 recently and I designed this just for fun for my 6 year old kid.

I used to have a minirocket like this when I was a kid and loved it, so I figured he would like it too.. and he does! As a matter of fact, I too still have fun playing with this thing :)

After printing, just add a #8 threaded rod (cut bolt) with a couple of nuts for nose weight, then just add a little cap (get it at dollarstore) at the end and throw it in the air. As it touches ground, the cap will pop with a nice BANG and a little smoke. Instant smile on kid's face :)
