Simple 3d printed model rocket

This is a 3d printed model rocket that fits 18 mm solid rocket motors. I've used it with c class motors.
When you build the rocket, glue the long tube onto the fincan. Then glue the small square piece with the hole onto the bottom of the nosecone. Tie a rubber band between the two small holes on the body tube, then onto the small piece on the bottom of the nosecone. Add a parachute or streamer if you want, but remember to add protective wadding to protect the parachute.

Model rockets are dangerous, I am not responsible for any damage to property, persons, or animals. Use good judgement and follow all local laws.
