The file 'Stellated Octahedron 3D Printer Model' is (skp,stl) file type, size is 6.5KB.
I made this model in sketchup following instructions found in the video http://mathforum.org/sketchup/videos.html. Bonnie Roskes (of 3DVinci) made this video, and has many other excellent sketchup tutorials on the site: http://mathforum.org/sketchup/index.html.
There is a nice page for this shape on Wikipedia as well: http://en.wikipedia.org/wiki/Stellated_octahedron
