I've been experimenting and playing with my new 3D printer (Deezmaker Bukito) and I've both finally got the thing pretty much dialed in as far as printing goes, and also started figuring out how to model objects using OPENSCAD. I created an OPENSCAD file to create any size elliptical nose cone I want - I simply change the diameter and ratio of length to diameter in the file and render it - the cone renders with attached shoulder and a bar across the opening for shock cord attachment. The nose cones are hollow with a 1mm shell. My portable scale is on the fritz right now, so I'll have to wait until I get to work tomorrow to actually weigh the nose cones I made, but I printed three nose cones this weekend. An NC-50X (the nose cone used on the Sprint), an NC-20B (the nose cone used for the glider portion of the Orbital Transport) and a BT-5 downscale of the NC-20B. They aren't perfect, but a little sanding and they will work just fine. These are printed in natural color PLA (my printer doesn't have a heated bed, so ABS is out), but you can get a pretty good idea of how they look in the attached picture. If anyone is interested, the two larger STL files and the OPENSCAD source file are posted on the Thingiverse now: https://www.thingiverse.com/thing:507830
