3mf files for bambu slicer

[Matthieu Hendriks]

 Has anyone successfully created 3MF files from PythonSCAD with per-object colors that retain the color information when imported into Bambu Studio? I can generate 3MF files, but importing them results in an error stating the file is not a valid Bambu file, and only the geometry is imported.  

And if yes, how did you do that :)
