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?
