I designed these chess pieces to go with a stone chessboard left to me after my grandfather passed. I took it as an exercise in creating simple designs that fit within the same theme.
It might be a good idea to apply felt to the bottom of each piece, as they slide around easily. All of the pieces are in one 3mf, though to make it easier to print, they are all separate objects/instances.
