Abstract: An article has first and second substrates with a spacer between them. The spacer includes beams connecting a plurality of walls, with openings between the beams. The plurality of walls includes multiple first, second, and third portions. The first and second portions are not parallel and have top and bottom edges that define a height of the wall and contact the first and second substrates, respectively. The third portions have top edges continuous with the top edges of the first and second portions but a smaller height than the height of the wall. At a given plane intersecting a first or second portion and perpendicular to the top and bottom edges, the thickness of at the top edge is plus or minus ten percent of the thickness at the bottom edge. The third portions are connected with some of the beams connecting the walls.
