I designed this emoji memory game in tinkercad for me and my dad to play.
I included blank tiles so you can add your own SVG faces by importing them and making them 16mm X 16mm and 0.4mm thick and 0.4mm raised from the surface, then align it with a tile, cut out a hole with it, then create a duplicate solid part to fill the hole
The case that I put them in is the “Just In Case” with the “JUST” removed from this model: https://www.printables.com/model/265985-just-in-case-pun-box
