Tic Tac Toe in a box

Easy to print without supports

Print one base and lid, and 5x Cross 4x Nought

OR print four of each and one each of the centre cross and centre nought pieces that fit together to make a piece that is a nought one way up and a cross the other :)

Make sure you have 'print thin line' checked when printing the box

Use some 1.75mm filament for the hinges
