perhaps make a small edge between the square area and the wooden part of the bord, just beveling the woodarea would be suficent perhaps, also most chess boards Ive seen have numbers and letters on the sides ( A,B,C,D,E.. 1,2,3,4,5... ) as a positioning system, which also is essential when playing blindchess.

Ok, I'll put a "rim" around the part with the squares.
As for the A,B,C... 1,2,3... I never liked them, it makes it look like a baby's toy ;) .
Thanks anyway.

Here are the final models.
