Hebe - Flying Model Rocket

The 3D Printed equivalent of Juno from Make: Rockets by Mike Westerfield.

The body tubes and motor mount can be printed in vase mode to maximize strength and decrease print time, as well as decrease print time. If you are using the faster print version of the tube coupler, it can also be printed in vase mode, but the regular tube coupler can not.

The fins should be placed 120° apart, with the launch lug at 60° (in between 2 fins).

Inside Assembly:

The motor block should be a little under 2.5 inches from the base of the rocket, as the motor should stick out around ¼ inch. Proper positioning can be achieved by coupling the tubes together, then inserting the anti-warp tubes, then the motor block. Parts can be glued together with some sort of plastic glue (i.e. 3D Gloop!) or another strong glue, but may need some sanding to get together.

If it has a tighter fit than the motor, the nose cone should be sanded to reduce friction. Tape can also be added to the motor to ensure a tight fit.

Print the nose cone with 25% infill to ensure stability.

This rocket can fly up to 1,600 feet, or about 490 meters (on a C6-7).

As the rocket will be traveling fairly fast at the end of its burn, motors with the longest ejection delay (A8-5, B6-6, or C6-7) should be used to get the maximum altitude, although regular motors should work as well.

You will still need a parachute and shock cord, but the motor should pressure fit without an engine hook, and there is a block to keep it from going too far in.

The shock cord should be 2 feet (0.66 meters) long. A 24-inch streamer should also be used.

When launching, make sure to launch it properly (away from power lines, not when an aircraft is flying close, count down from 5, etc.). I am not liable for damages caused by improper use.

This rocket can use A, B, or C rocket motors, and is designed to fly from a standard 1/8th launch rail, like the one that comes default with beginner launch pads.

Happy flying!
