A traditional board game from Madagascar, popularized by Assassin's Creed: Black Flag. Folds for part storage and travel.
Pause the board prints at 1mm to change filament colors, and you'll have nicely-contrasted movement lines. You will need to print the pucks twice, one set each in different colors.
No supports needed. Prints well with .25mm layers.
