Exponential horn generator

cults3d

This is an exponential horn library for OpenSCAD. I made it to amplify sound from my son's watch alarm (fittings for that are available here). You can utilize this library in your projects or simply generate horns with the demo Customizer located here. To create a horn programmatically, use <horn.scad> and call horn(). Additionally, you will need my tubemesh library, which is bundled in the demo. There are numerous optional arguments: length = x: horn length, from mouth to throat throat = [w,h]: width and height of throat (narrow end) mouth = [w,h]: width and height of mouth (wide end) wallThickness = x: wall thickness numSections = n: number of strips used (more is slower but better quality) rectangular = b: set to false for a round/elliptical horn (very slow); default: true flangeLength = x: flange length around mouth, for mounting mouth into something; set to 0 to omit flange flangeFlare = x: how far the flange flares out
