Parametric Nose Cone Adaptation

thingiverse

Stuphi created a beautiful nose cone scad model that generates the basic nose cone shape. This scad file wraps the nose cone library with some utility functions to control wall thickness, shoulder size, and a hole for mounting an eye bolt. I've successfully used this to make various nose cones. Pictured are two different sizes that fit standard paper roll tubes, and a replacement nose cone for the Estes Flutter By. To get the required nose cone shape library, visit one of these URLs: - https://github.com/stuphi/NoseCone - https://www.youmagine.com/stuphi/designs Note that some adhesives don't work well with printed plastics, so make sure your shoulder piece is well-secured to the nose cone. The ridges from the layers actually help here since they provide space for the adhesive to lock in place. Also, ensure you get good layer adhesion. There's not a lot of shearing force on the nose, but it wouldn't be good if it came apart in flight. In most cases, you'll want to secure an eyebolt to the shoulder using a fastening method that will never come loose (epoxy on the nut inside is one way), and then glue the shoulder into the nose cone (add weight first if necessary).
