Putting flipped plates together as close as possible I have two plates that I would like to connect together and collapse with the studs facing out like in the image below. I need the two plates to sit as close together as possible. But I'd like them to open up fully so all the studs face the same direction as well.
I came up with an idea with horizontal clips and a bar (shown in image). Or maybe using a hinge plate, but then I need to reverse the studs which takes some space.

Any idea how to do it as thin as possible?
this way it can open and close


Blue = 4276 Hinge Plate 1 x 2 with 2 Fingers
Yellow = 4275 Hinge Plate 1 x 2 with 3 Fingers
LightBlue = Plate 2 x 4
White = Plate 2 x 2
Pink = Plate 1 x 4
Light Bluish Gray = Plate 1 x 3
Yellowish Green = Plate 1 x 2
Red = Tile 2 x 2
Green = Tile 1 x 4
