Okay so it isn't really a cube, but that doesn't make it any less awesome. This nifty little thing was created by Kris Pister at UCLA and basically tells you everything you ever wanted to know about silicon (from a microfabrication standpoint) i.e. different crystal planes, etch rates in various solutions, crystal structure, etc. The original is made out of paper and meant to be glued or taped together, but after an unfortunate incident involving a falling textbook I have discovered that it is not very robust this way.

On the off chance that you don't actually care about silicon but want to print it anyway, it makes a nice Christmas tree ornament!

I've included a hollow box version with a lid, a braced box version, and a full-blown solid version, depending on how much plastic you want to use.

Update: I uploaded a letter-sized version of SiCube.pdf (the cube itself is still the same size). I also uploaded new pictures since I totally made the first one wrong =(.

If you are printing a box version, print the lid and one of either SiCubeBox.stl or SiCubeBoxBraced.stl. Glue the lid onto the box. Print and cut out SiCube.pdf (you can cut off the glue tabs) and glue the pieces onto your printed cube.

If you are printing the solid version, you only need to print SiCubeSolid.stl and glue the paper pieces as above. As an added bonus, the solid silicon cube can also be used for self-defense.

I've only printed out the hollow box version so far and there is some warping on the sides but nothing too serious. The braced version should fix this.
