Tic-Tac-Toe Set

Sometimes you just want the simple game, ready to go, without digging through a drawer for a pen and paper. This is the whole thing printed — a 69 mm board and ten playing pieces, five X and five O, so each player's side is instantly readable in two colors. Three plates, about an hour, and 17 g of filament. Nothing else to source.

Five 3MFs and three STLs. There is a project per plate so you can print exactly the build you want — pick one of the two bases, then add both piece plates. An all-in-one project is in there as well.

The 3MFs are the faster path — each one carries the profile that plate needs. A full print & play guide is attached to the Creality listing.

Three Plates, One Game

A game is three plates, not four. The two bases are alternatives — print whichever one you want, then add both piece plates. Every figure on this page is that three-plate build.

The Board
68.8 × 68.8 × 3.5 mm. Comes two ways: a single-color base at 21 m and 8.60 g, or a two-color base that picks the grid out in a second filament for about 3 minutes and 0.88 g more.
X Pieces
Five of them, 19.8 mm across and 5 mm thick, all on one plate. 22 m, 4.27 g. A game needs four, so the plate prints one spare.
O Pieces
Five of them, 19.5 mm across and 5 mm thick, on their own plate so you can run them in a different color. 23 m, 4.26 g.

Slice It Right

Everything here is a flat part printed face down, so there is nothing to bridge and no supports are needed on any of the three plates. Run the pieces in two colors and the game reads at a glance; run the base in a third if you want the grid to stand out.

All five projects carry identical settings: 0.10 mm layers with 2 walls, 9% gyroid infill, 5 top and 3 bottom shells, and a 5 mm auto brim. The fine layer height is what keeps the X and O edges crisp at this size — it costs very little on parts this small.
