Here is a cruise missile-inspired model rocket I designed. I made it square because...well why not? It is setup to be printed as one whole thing, and I have included the individual stl and solid works part files if you would like to tweak the design to your liking. I have not printed it yet, but I will try to get it done this week. Not flight tested either, but it should be stable. If not, you can tell me how I can improve it.
P.S, I found out that I can't spell missile correctly. Hmm...
Print out all parts with 30 to 50% infill. sand and fit all parts together. Make sure all of the sections are lined up straight and parallel before gluing with CA(super) glue. Leave nose cone unglued, and attach your streamer or parachute to the provided cross bar. Glue the other end to the inside of the rocket body, taking care to leave enough space to fit he nose cone on. Bend a paper clip to hold the rocket motor in place. I designed it for an A8-3 motor, but you can tweak the design as needed, or let me know and I can deepen the motor hole.
