Small Tic Tac Toe board made to use ~10mm x ~3mm magnets for your fridge.

Made in Fusion 360, but I am including several file formats so you can edit as needed as easily as possible for whatever size magnets you have access to.

I am a Klipper user and have two Ender 3 v2 printers running - GCode is included but per usual, it is advisable to create your own.

I used https://www.amazon.com/DIYMAG-Refrigerator-Magnets-Premium-Brushed/dp/B08GLS59JS/ref=cm_cr_arp_d_product_top?ie=UTF8&th=1 and they fit perfectly.
