Little Dorky Designs’ officially licensed ForgeCore design turns a chess set into a sushi platter: pawns are wasabi and ginger, rooks are tuna rolls, knights are salmon nigiri, and bishops are shrimp tempura, each piece 3D-printed in PLA. The board is a roll-up bamboo-style sushi mat that folds in half and, with the pieces, stows inside a bento-box case — $69.97, shipped from the maker’s shop in North Carolina.
