This design was fun to create and is a hoot to fly.

The rocket is tiny but kids and adults love it. it won't fly very high on A engines but B are fine.

The main stage and the fairing feature a little bar to tie them together and tie the chute.

This prints in one go, no need for infill or supports, the main stage has a support that can easily be cut off. I recommend printing with an 8-line brim so the print remain stable as it builds higher.
