Mini magnetic chess set for mint tin (with checkers alternative)

This is a simple chess set i designed to fit inside a mint tin for gaming on the go. It's designed so that the magnets inside the lower half allow it to stick to the outside of the tin where I taped a 8x4 checkered grid to each side. These pieces are made to work with 2.5mm magnet balls, but similar ones will probably work. These pieces can work on any size of mint tin but the smallest tin I recommend on is a 2.25 inch by 1.8 inch (59mm by 46mm) tin but at that size the gameplay can be a bit difficult, so try to use a larger one like an altoid tin.
