This is thingiverse user dom's laptop stand (from this comment: http://www.thingiverse.com/thing:32#jsid-1237162568-10), with the Hokusai Wave pattern. These are dom's improvements over the original laptop stand design:
It fits my 15" Macbook Pro perfectly (only problem is that I laser-cut the notches too wide; jamming a piece of paper in them fixes this - no more wobbling).
