I combined both styles of the original model's case as I preferred it this way. Both STL and STEP files are provided.

The case needs short M3 brass inserts like these. You need to drill the m3 holes on the lid, as I included a layer so no supports are needed. To close the case 4 M3x8 screws are used.

The lid model includes the letters if you want t print multi-color as in the picture I provided (you need to use the “split into objects” option on PrusaSlicer). Several tutorials exist to print multi-color on the first layer if needed. If Requested I can provide the prepared gcode file to print that way.

I hope you like the models! If you want to support my work you can Buy me a Beer!
