I made a pair of these stands to hold my chopping block (1.5" thick) vertically while drying and/or for storage. The weight of the board on the living hinge cause the support to close on the board.
I printed this on its side with support material. Removing the supports from the tighter gaps was a pain but do-able. Wouldn't recommend trying to print without supports.
