Calculix-style bricks

Calculix-style bricks. The numerical value is also the height. Basically, it's an educational game for children to learn addition. If you stack two or more numbers on top of each other, they are at the same height as the addition result. By just comparing the height, you know the result. I've seen an advertisement of Calculix and immediately thought "that I can design and print myself" and here we are.
