This s a 2-dimensional puzzle based on a 3D idea of Thomas O’Beirne. It looks like the 11 all different pieces fill the tray as it comes, yet the small 12th piece that comes in its own separate spot can fit in the tray also. There are 159 solutions to fit the 11 pieces in the tray so that they fill the tray. There are even more ways to fit all 12 pieces into the rectangular tray, if you can just figure out how!
