Well, I finally got the 3D printer up and running, and I've been slowly learning to create objects (programming, really) in OPENSCAD. I've actually uploaded three designs to Thingiverse (kind of a clearing house for 3D and laser cutting designs, all downloadable for free). The first is a parametric elliptical nose cone - you change the diameter and ratio of length to diameter in the OPENSCAD file and render any size nose cone you want. I also uploaded a couple of standard Estes style nose cones as well: http://www.thingiverse.com/thing:507830
The second object (or "Thing" as they are referred to) is a parametric conical nose cone design. Same idea as the first but with a conical shape, also including a few pre-generated cones: http://www.thingiverse.com/thing:509295
Finally, the conical nose cones got me thinking about one of the really cool rockets using a conical nose: the Black Brant II. Great model and a great flyer, but that reducer is a real pain - not any more! I modeled the reducer and the tail cone and also included the NC-55BB from the conical nose generator. I'm really pleased with this one! http://www.thingiverse.com/thing:512113
I also plan to eventually reduce these parts so I can print a smaller version based on the BT-50 body tube and using an 18mm motor. I'm really excited about the possibilities using this thing! It will be even better when the company that made my printer adds a heated bed so I can print with ABS instead of PLA (which is a real pain to sand and can't be vapor-smoothed like ABS can).
