Magnetic Modular Chessboard (OpenLock Compatible)

This is a grid board that can quickly change into any size, is portable, and can reflect different grid patterns. The board consists of individual squares that are different colors on each side and connect together with either openlock connectors or magnetic clips. This allows it to be configured in a ton of different ways and easily broken down.

The key features of the board:
1. The size of the board could change depending on the game you were playing. For example, a 5x5 board for Tak or Santorini, an 6x6 board for The Duke, or even a 10x10 board for playing amazons.

2. I wanted the pieces to be able to flip to change the grid pattern. For example, in arimaa there are four hole/pit spaces while the rest of the board is the same. I printed the board in the pictures with a wood filament that I then stained different colors on each side so the pieces could be flipped in place. I preferred a more subtle contrast between the colors; however, you could make it whatever colors you’d prefer. It would also be easy to swap filaments half way through printing to make the squares two-toned without needing to paint anything.

3. I wanted it to be easy to re-configure and break down. The board can be held together with standard openlock clips ( for a rigid structure or with magnetic clips. I included a special version of the magnetic clips that cover the edge of the squares. Depending on aesthetic preferences, the board then doesn’t require the edge pieces.

The Magnetic clips use 3 by 3 mm barrel magnets:

Here is our Tak Table. The board can easily break down and fit in the drawer alongside the game pieces. It is also easy to throw the board into a pouch for the gamer on the go:
