Chess clock

###The chessboard

The awesome wobbly chessboard shown in the image, and its belonging pieces, are designed by [MikeyB](https://www.thingiverse.com/thing:53604)

I did however alter the base of the pieces to be a bit more hollow, and I removed the last couple of layers. This way the pieces always stand upright and give the magnets inside a stronger pull force. I've included the new base file (New_piece_base.stl).
