Keychain with the iconic letters from the SUPER MARIO video game. It includes the monochrome version. In the color version with separated letters, you can fit them together, but since it’s a keychain, I recommend adding a little glue.
 

Both the AMS version and the non-AMS version are included, as it is divided into trays by color. 

A single-color version with outward relief is also provided. If you prefer the relief inward, simply choose the color version and remove the letters and if you want a smaller version, you can modify it in Bambu Studio.

You can find the keychain version and a larger decorative figure in my profile.
