@tobles If it kinda worked, you might need to do some manual ‘fixing’. For instance, it can happen that some (or all) of the rectangles are ‘twisted’, in this case use W > Loop Tools > Flatten (Loop Tools is an Addon, that comes with Blender) on those.
If you are more or less happy with the result, just duplicate the rectangles, cancel the transform, P > Separate by Selection, and make them into metal plates.
