About this 3D model

I found Lawsy's design fantastic, but I only had 1/2" magnets on hand, this should be a redesign to accept them. That being said, I haven't had a chance to print it yet. Based on Lawsy's work: http://www.thingiverse.com/thing:30828 EDIT: For use in repetier host, I had to scale in all directions times 10. Just an FYI.
