ShengShou Square-0 (Mirror Slice)

The ShengShou Mirror Square-0 (Mirror Slice) is based on the square-0 design which is a square-1 with no edges. This one has  different-sized layers to turn it into a mirror cube!

Please note that all of the pieces on each layer are the same size, so it is only "mirrored" on one axis.

Solved by shape, not by color.
