Description

A 9×9 Go board for beginners and quick games, in a 190 × 190 × 28 mm body. The top is a stepped deck: the 170 mm playing field sits above a 6 mm terrace at 4 mm and a 4 mm outer terrace at 2 mm, like a quarry cut. The grid is not grooves; the top 0.8 mm is a second filament colour with line slots through it, so the lines are flat and stones do not catch.

Under the deck sits a drawer, 171.6 × 180.5 × 18.6 mm, with a divider. It holds the 81 stones (41 dark, 40 light), and magnets hold it shut. Stones are 18 mm discs with a rounded top, a little smaller than real ones to fit a 19 mm grid.

Print colours: beech wood PLA on top, slate or black below and for the lines, charcoal and ivory for the stones.

Why it sells

This is a taste pick, not a sales one, so there is no ranking claim. Free Go sets already exist on the printing sites: a complete 9×9 set with board, bowls and stones on Printables, a portable set on MakerWorld, and a 9×9/13×13 board with drawers that you glue together. Wood sets are sold by retailers such as Yellow Mountain Imports. The gap: none of the ones I found has a flat two-colour grid and a quarry-terrace edge as a design object.

Who buys it

A Go beginner who wants a small board, a person who gives game gifts, and a desk-gaming owner who wants it displayed on a shelf. Etsy, MakerWorld, Printables.

Design overview

• 9×9 grid at 19 mm pitch, 152 mm across, five star points.

• 190 × 190 mm footprint fits a 220 mm bed.
