OpenJSCAD
I love OpenSCAD for everything but the language, which is .. so bad that the rant stays corked.<p>Perhaps the 3MF  <a href="https://github.com/3MFConsortium" rel="nofollow">https://github.com/3MFConsortium</a>  output format could be useful too?<p>Edit: ah, i didn't see any dates; but I do see a "Google+ community" link ... Perhaps there's more to be done to make this a viable alternative.
