After fixing my cube and gluing parts together, the model became much more legible and easier to understand. Because I did not use glue to assemble the model initially, many of the heavier pieces began to fall and slope, and some of the pieces which had been damaged from assembling and disassembling so many times got warped and began to slide around within the slits. However, I am much happier with the stable cube because every layer is now visible and much more interesting.
