How can one split a module in two, then give them different colors and after that slice and print it (as “one” single module?").
@mailroscano I’m obviously not familiar with your model, but typically you would use the paint tool in Bambu Studio to color the sections of your module. It actually works quite well, I use it all the time.
I use Orcaslicer.
Another way is to save the different coloured parts as 2 different stl files.
Then pick both files to import into the slicer.
You will get the below… Pick YES
Edit: Forgot to add…
Once you have added both objects to the slicer, go into the Objects tab (near Global). Pick your first object then the number of the filament you want it printing in. Do the same for the second object
