kiveva spiral knot 3D print model

I wrote a sculpture generator and am posting some files created by it. They can be used for rendering of course, or 3D printing by a machine that doesn't need integral supports (e.g. one with soluble support material or powder support). They can be printed with or without color. This is a color by vertex VRML file. It does not have a texture map or unwrapping, just a color assigned to each vertex. I can convert to an OBJ file with a texture map if needed, but it still won't have unwrapping: the texture map will just be pixel hash that could be used for recoloring the existing pattern, but not to repaint the model.
