Thorn Rocket

This is my design of a model rocket. This entire rocket can be printed without the need for any supports. The Rocket is 12 inches long with a diameter of .875 inches. Flies up to 1200 feet on a C6-5 Engine and 600 feet on a B6-4 engine. There is a place inside the body tube to tie on a shock cord. I would recommend using a 9 inch parachute or a streamer for the recovery. The parts may need to be scaled in the slicer, I had to scale by 2540%. Make sure to print the fin tube with the fins in the air and not the build plate. I also used a brim for each part to help with bed adhesion. Once every part is done printing you need to attach the fin tube and body tube together with the coupler. The chamfer on the coupler should go into the fin tube. I used spray paint for a smoother finish but it would be fine without it.
