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 3 parts. You can make it as long as you want as long as you adjust the CG 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 seemed to work better or ABS should be able to handle the temps a little bit but tolerances are a little snug so watch for warpage or shrinkage. I printed 1 exterior wall to save weight with lower infill density. This thing flew like a bat outta hell so start I'd with a B size engine if making it smaller. The video above shows a C6-5 engine. Happy flying! https://youtu.be/D7rTwgUM1-o
