Summary

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

Instructions

In addition to following Bonnie's instructions, I had to remove the internal polygons that form the octagon in order to create a clean STL file. When I skipped this step, I ended up with a model with a hollow center - interesting, but risky to build.

Thanks to YouTube user therealtechknight for posting a HD video of a makerbot creating the Stellated octahedron! http://www.youtube.com/watch?v=8Y6ZmXBmBZ8http://www.youtube.com/watch?v...

This is really nice but I have been having a lot of trouble getting the piece to stick to the raft, because it has a very small contact surface. I might try cutting it in half. and printing two pieces.

I had no problem getting this to stick with stock settings, however I do have to dial the raft in so that it is just right. It's pretty amazing to see the model build up from that first thin line. Good luck!

First stellation of the rhombic dodecahedron is very pretty too!
