That looks nice--simple and convenient. I made something similar, but 3D printed with magnets:
Printable chess set (board and pieces)

It's easy to generate your own. See https://www.alt-codes.net/chess-symbols.php and/or https://en.wikipedia.org/wiki/Chess_symbols_in_Unicode

Hey, can I get an image for the printable chess pieces?
Here it is: https://davemullenjnr.etsy.com/listing/1557517889
Made this recently and was pleasantly surprised at how easy it was to get up and running and even more impressed by how useable it is. I imagine it'd be even better if you were to laminated the A4 sheet before cutting.
Is this something that anyone would be interested in?
