Horn OpenSCAD

This is a horn for a speaker system that I have yet to make , in OpenSCAD only, as it is a work in progress. I've put in lots of user definable parameters to make it fun to play with. Sooner or later I am going to design little 3D printed things to hold all of the 1' to 3' speakers that I have in my parts box, that were torn from those speakers that came with a tower computer, as the windows '95, and so on had to be replaced with a better computer, that also came with a pair of speakers that I didn't need.
