If I open blender, I see a 2mx2mx2mm cube by default.
But, once exported to stl and put into cura, I get a tiny cube of 2mmx2mmx2mm.
Also, when I import it back to blender, it still a 2mx2mx2m cube.
Fortunately, I still can export the model providing a 1000 scale factor to get the correct dimensions.
And I also need to apply a 0.001 scale factor when importing
This feels cumbersome. Fortunately, I can also change the scale of the metric system of blender to avoid this hassle.
Once blender has a unit scale of 0.001, I can save this setting for the next time.
