The size of the chessboard is 225*225mm, with a line spacing of 15mm in both the horizontal and vertical directions

At the beginning of the design, I planned to insert a magnet for magnetic attraction, but the cost of buying a magnet was almost as much as the price of the finished product on Taobao. So I just kept the hole for the magnet, with a diameter of 3mm. I haven't tested whether the magnetic attraction works or not, so everyone should think carefully before making a decision

If you think the chess pieces are too small, you can adjust their size appropriately. It is recommended that you print a few pieces first to test it out

The size of the chessboard is quite large, and it will be a bit deformed and uneven when it's printed out

We will release a 10*10 version in the future, which will be more convenient for A1mini to print
