I designed this to be compatible with the A1 Mini with NO AMS.  Each plate is a single color and all parts are assembled afterward.

Only the TNT letter cutout requires supports (already set in 3mf).

Colors: Red, Black, White

Assembly:

For steps 1-3, glueing is optional but recommended.

1. Seat the bottom inner shell into one of the outer shells.
2. Slide the middle TNT cutout over the bottom inner shell.
3. Slide the top inner shell into the other outer shell.
4. Glue letters and squares into their respective cutouts.

I hope you like it.

Enjoy!
