Re-Revised 3x2x1 Rubik's Cube

This is nearly identical to my prior version http://www.thingiverse.com/thing:3485 . It's been slightly altered so that instead of totally hollow external cubes the interior sides come up to a point - so that there is a minimum 45 degree angle support for the top part. The next version I upload will have totally solid cubes with additional improvements discussed in this blog post http://makerblock.com/2010/08/revising-the-3x2x1-rubiks-cube/

All parts are contained within a single STL. Make sure your build platform is centered as closely as you can - the STL is nearly as wide as the full platform. Before converting to GCode, I used RepG to center the STL - you should too just in case.
