An 1/3rd semi-scale model of a WWII soviet Katyusha rocket that actually flies. Goes several hundred feet on 10 N*sec engine, easy to assemble, easy to balance. All parts save for engine tube are reusable (the tube melts when ejection charge fires).
Assembly:
1) Print all parts except tip and cord mounts in vase mode. Tip is printed with 100% infill. Cord mounts are printed with whatever infill you like.
2) Insert the narrow part of Upper_Ring in the Body and glue.
3) Insert the Engine_tube_mount halfway into the tail and glue. Glue a piece of paper on top of it (prevents the plastic from melting when ejection charge fires).
4) Insert the part of ENGINE MOUNT that sticks out of the TAIL into the other end of the BODY and glue.
5) Insert nosecone cord mount and tip into the respecting ends of the nosecone. DO NOT GLUE tip — you may need to add ballast into the nosecone. Glue cord mount.
6) Glue launch lugs onto the body.
The writing says "For Leningrad". Leningrad was a city where my
