Multi-Coloured Text on the Top of a 3D Printed Box Lid

Hello

I am working on a project to produce multiple (x12) small 3D Printed Boxes, and I would like some text, a logo and the number 01-12 on the lid. I have the STL file for the lid and need a Black Square inserted into the top of the lid (Bottom of the print as printed upside down) with the text, logo and number inserted into it. It needs to be flush and not raised or embossed. The first image attached shows am UNO Card box with the type of thing I need. The second image shows the box and the third what needs to be printed on the top of the box lid.

I use a BAMBU X1C Carbon and BambuStudio. I need to just be able to open what you make for me, allocated the filament colours, slice and print. My tech knowledge of 3D printing is VERY limited! lol

Need this within a couple of days please.
