This is a parametric laser cutting template for the classic Connect Four game made with OpenSCAD.
Modify the parameters at the top of the OpenSCAD to suit your needs, export and cut it.
To assemble, begin with the board spacers, these are the narrow pieces with protrusions on either side. Glue them to the board faces on the inner rows. After that has dried up, glue the board between the two stands. Finally, glue the closing panel to the bottom of the board.
Note that Laser Cutters do not cut colors. To actually make the game playable, cut half of the play pieces from a different material or apply some paint. :)
The game is played by two players that each take turns. Each turn, a player takes a play piece of his color and slides it into one of the 7 slots. The player that can create a continuous line of 4 pieces either horizontally, vertically or diagonally wins.
