Proper subboard for uploading starter or utility models for non-graphical purposes

My contribution will be a large uv-sphere and icosphere pair useful for mapping the geography of planets. Writers and worldbuilders will gain the most benefit from it.

Is there a proper subboard here for such a thing, or should not bother posting it to blenderartists.org at all?

Are you suggesting something like a BlenderArtists.org asset library? (just trying to make sure I’m reading correctly)
