This stand is for a 2-sided sign made of a sheet of US Letter paper folded longways.
I've redesigned my previous paper sign stand so that it prints much easier and stronger. All of the pieces can be printed flat and no longer wiggle themselves apart on older printers.
All the necessary pieces can be printed on a standard Prusa bed, though it's tight on space.
The author remixed this model.
Basic shape is the same, but redesigned how the arms connect to the base. It allows it to print flat on the bed.
