new / replacement rocket for foot powered air rockets. While looking for the picture of the kids toy i modeled this for, i saw many similar toys that were almost identical so this rocket model will probably fit most of these similar toys. ID of the rocket is 18.6mm as modeled should you want to scale it to fit your launcher. 

why does it have 5 fins? because that's how many my kid wanted. 

Printed in PETG, 3-4 walls 20% gyroid infill. the body tube and fins are 3 walls thick on a 0.4 nozzle and should print without infill. Upon printing the model was a bit heavy, you may want to slice with less infill and walls for a lighter model. 

WARNING: this model will likely be heavier than the original, and will have a hard point instead of foam. Its basically a lawn dart so be careful. We were able to regularly embed the nose a half inch or so into the ground.
