A travel case made to fit the black knight puzzle board by georgmierau. The board slides in the top as the lid. It has some extra room in the base for more pieces for more scenarios to keep the fun going after the initial solve. May add a more compact version later. I printed this with the board, both scaled at 75% and it fit well with a satisfying click.
It is also quite loud and rattly so I might add an insert or recommend padding.
