How to run this session
Stages and timing

- Add the board dividers
- Make five separate X pieces
- Make five separate O pieces
- Count and check the fit
- Play and collect the complete set
What gets built
Create a complete small game for two players.
What it practises
- Bonding fresh PLA strands on a flat support.
- Repeating the template and checking the fit.
- Playing a game with the complete set of pieces.
Success criteria
- The set contains exactly 11 physical parts: 1 board, 5 X pieces, and 5 O pieces.
- The board measures 12 × 12 cm and has nine cells; the frame, dividers and their joints form an integral whole after cooling.
- Each X has a bonded center and each O has a closed outline; the pieces remain separate integral components.
- Every symbol fits freely in every cell without being forced in, bent or caught on the dividers.
- Two players play a game from X's first move to a win or a draw without making any additional pieces.
- After the game, the complete set is still available for the next game.
