Here the Euro version of 10 in a Square (https://www.thingiverse.com/thing:4790683).
As it is valid for the original, you can use Prusa Slicer or other slicer to make a color change for the letters. Otherwise, just leave them and they will print in the same color as the rest of the model if you print the v4 Version.
Additional you need 10x 1-Euro-Cent coins. Goal ist to place all coins next to each other in the square. The solution is shown on the 3rd and 4th picture
Have fun and thanks to @MikeInAZ for the original design.
