Rocket A-1 - 3D printed flying model rocket
Rocket A-1 is a fully 3D-printable flying model rocket. It is threaded, so it doesn't require
any glue to be assembled (except a little drop to attach the parachute or streamer cord to the cone (but I'll
probably add a hook in the cone in incoming version to avoid this inconvenience)).
It is compatible with Klima motors (18mm diameter and 70mm length). It was tested with Klima C6-7 motor and flew
nicely - the same model is ready to fly one more time.
Feel free to modify the model and create your own version best suited for your motor :). I'd love to see more
A-1 fly!
How high will it fly?
Simulation from the OpenRocket (included below) shows something about 220m. I didn't put the altimeter inside yet, but I guess it could have been something around it.

How to 3D print the rocket?
I printed the rocket on Ender 5 Pro. There's a possibility that your printer will require some adjustments in *.stl files to be able to print them properly. It's good to use quite a big brims while printing fins - unfortunately they are quite likely to collapse and create not-so-nice PLA spaghetti grimacing I used PLA to print it, but ABS should be fine too. The rocket survived its first flight and it's getting ready for the next one, so PLA seems to be tough enough :).
You can find full schematics & designs in the Github repository. Fly high!
