• and
• at least three connecting ribs between the at least three posts;
• wherein first ends of the posts define a first plane;
• and
• wherein second ends of the posts, that are opposite to the first ends thereof, define a second plane;
• wherein at least one of the posts is length adjustable,
• wherein the at least one of the posts that is length adjustable defines, in combination with a further post of the at least three posts and two connecting ribs between the post that is length adjustable and the further post, an adjustable trapezium having a single length adjustable side defined by the post that is length adjustable;
• and
• wherein said adjustable trapezium is configured to set a relative orientation between the first plane and the second plane and to thereby set an orientation of the adjoining framework relative to the framework.
