The 3D model of the classic game Tic-Tac-Toe consists of a base designed to hold 9 cubes arranged in a 3x3 matrix. Each cube has two faces: one featuring a circle and the other an X. These symbols are embedded into the cubes, requiring no adhesive for assembly. For optimal results, it's recommended to use PLA filament to print the cubes and PETG filament for the insertable parts, ensuring a snug fit and durability.
