Now I added the chess notation and placed the peices on the board so the model looks closer to the real setup. I also added the magnet at the bottom so I can plan how it will pull the pieces from under the board. I made a few small tolerance and fitting changes, like adjusting the holes and spacing so the parts should fit better when printed. This helped me check if the board, pieces, and motion system all have enough room to work together. Next, I want to keep testing the fiting and make sure the magnet can line up under each square.
