Celtic Chessboard Box Remixed

I remixed a chessboard/box that i found here: http://www.thingiverse.com/thing:41792
It was listed as a work in progress, had a few open gaps, and the Celtic symbol stood too far out to balance pieces, so i reduced the height of the Celtic symbol block to something a bit more suited for my chess pieces. I also made a negative/gap so that there are two sides to the box that slide into one another, it may be a tight fit. The total slide over gap is 7mm, should be enough to keep the box closed.
