NOMOON is a parametric spherical 3d-printed speaker generator created in OpenSCAD.
For a demo video of NOMOON see: http://youtu.be/UFUMgY15UOw
Some additional notes are on working with NOMOON are athttp://nothinglabs.blogspot.com/2014/12/project-nomoon-parametric-spherical.html.
It is loosely based on my previous OpenScad speaker generator - Speakergenhttp://nothinglabs.blogspot.com/2014/09/speakergen-parametric-3d-printed.html.
NOMOON can create spherical speaker enclosures of any volume. You can configure things like wall thickness, bass port dimensions, number of screw holes, etc.
NOMOON also includes a speaker stand. If your speakers tend to rotate forward in the stands - strategic application of a rubber band can solve this.
