25mm carbon fiber tube rocket

thingiverse

I had some spare 25mm carbon fiber tube laying around, so I decided to print a few parts and turn it into a model rocket! I wanted it to be as simple as possible, so it's designed in three parts. You can make it as long as you want as long as you adjust the center of gravity accordingly. Since the tubing is so light, it tends to be bottom-heavy, so you'll want to fill the nose cone with ballast. I used a kevlar cord for the parachute shock cord. Simply tie it to the base section mount prior to gluing it to the tube. Run it up the body tube and to the parachute. I then ran a separate cord from the nose cone to the chute. The base section has a tendency to get soft if using PLA, but does still work. PETG seems to work better or ABS should be able to handle the temperatures a little bit, but tolerances are a little snug, so watch for warpage or shrinkage. I printed one exterior wall to save weight with lower infill density. This thing flew like a bat out of hell, so start with a B-size engine if making it smaller. The video above shows a C6-5 engine. Happy flying! https://youtu.be/D7rTwgUM1-o
