OpenScad Parabolic curved cone or tapered horn
thingiverse
OpenScad parametric function to create a curved and tapered cone/horn that follows a parabola. This was an experiment in figuring out how to make a tapered cone that bends after searching and being unable to find a solution. The test was a rough draft, so it's not elegant yet. The curvature is defined by a parabola. The horn is constructed using thin slices of cylindrical disks that are hulled together pairwise. Hulling the ensemble didn't work because it would fill in the inside bend of the horn. A more general solution would allow defining an arbitrary curvature instead of a parabola, but my method requires knowledge of an analytic derivative. Please feel free to remix this code and drop me a comment so I can see what improvements you made!
