@Alohaa said in Part not printed as drawn:
I don't quite understand what it means that it's not solid.
In order for a group or component to be considered a solid, or manifold, every edge must be shared by exactly two faces, no fewer and no more. So no stray edges, no holes in surfaces or missing faces and no internal faces. To be properly 3D printed all faces must be correctly oriented, too. That means the white front faces must be facing the air and the blue back faces are toward the print media.
Nested groups and components will never be considered solids because they contain more than just edges and faces.
@Alohaa said in Part not printed as drawn:
What do you mean by that?
The edges and faces in the space between the object on the bottom and the one on the top are just loose geometry. Compare your model to the one I shared.
@Alohaa said in Part not printed as drawn:
What did you do exactly?
I exploded the groups inside the top level object, removed a bunch of stray geometry and other cleanup. the Solid Inspector2 extension helps to identify problems. It might fix some of it.
@Alohaa said in Part not printed as drawn:
The fact that I drew these parts in mm didn't cause any problems, or am I seeing it wrong?
It didn't in this case but you can create smoother curves and other small details if you need it.

Incidentally, I recently printed a part I had drawn in metres without scaling it down because I had forgotten it was in metres, and it printed correctly, which I was amazed at and still don't understand!
The .stl file you exported has no units. It's only numbers for the sizes. So you can export with the model units as meters and import into the slicer as millimeters.
