The initial upload of BrowserSynth is now live on github under
BrowserSynth is a browser implementation of StructureSynth which offers non-uniform scaling of any primitive and obj/mtl and gltf export so you can then render it in whichever 3D program you like.

All the scripts are included as example scripts
