This is a portable tic-tac-toe game set produced via 3D printing. It features a square gray base with raised edges and recessed grid lines, along with a set of detachable pieces: white circular tokens and black X-shaped tokens. All components can be neatly stacked inside the box, forming a compact square container that’s both easy to carry and space-saving. Printing recommendations: For the base, use a layer height of 0.2 mm, enable rafting, and print in a single flat layer; PLA filament is sufficient. This set makes an excellent desktop entertainment toy or an educational tool for young children.
