For easy print, just use my profile and set your preferred colors.
The main model and the print profile is created in layers, so you can print this also without AMS. Each layer uses one color only.
If you don't have AMS, you can change colors manually. Just as an information, my print profile changes colors at layers: 9, 11, 13. ( for 0.2mm layer height ). I've used 4 colors, but it's not mandatory, use what you like and have.
I've also included the simpler version created with Bambu Make my Sign, which uses only 2 colors. If you want to print this simpler version, download the file ‘MakeMySign model - profile’.

Print it bigger if you wish.
