Ultimate Tic-Tac-Toe

Your opponent's last move determines in which grid your next piece must be placed. (Ex. If your opponent places their piece in the bottom left corner of the middle grid, your next move must be in the bottom left grid. Then say you place your piece in the top right slot of the bottom left grid, your opponent's next move must be in the top right grid.) If you get 3 in a row in a small grid, place one of your large pieces on top of that grid to claim it. If you are sent to a grid that has already been claimed, you may place your piece anywhere on the entire board. Get 3 large pieces in a row to win the game!

The dimensions of the board perfectly match the bed of an ender 3 pro.

you need to print:
1x grid
7x large X
7x large O
1x group of 42 small x's
1x group of 42 small o's

Additional small pieces can be printed individually if some get lost.

Consider swapping filament colors midway through printing the grid for more variation between the small and large grid lines
