Tunable Rocket

Parameter tunable rocket for use with common model rocket engines. No supports needed. Airfoil fins.

I included STLs for common B,D, and F sizes. I like PETG 40% infill with a 3mm brim. High infill is important to make the nose heavier for flight stability (read about center-gravity vs center-pressure with rockets).

You can also fully customize the model using the OpenSCAD file, to engine sizes, body sizes, fin count and fin scaling. Just be careful not to make the fins too small (it's scary).

WARNING !!!
Rockets can fly unpredictably causing serious injury or property damage.
Users of this design must take full responsibility for all risks.
