This was designed to help declutter a cabinet that held a lot of Pyrex glass bowls that nest inside each other. Now I can stack 4 full sets in a much smaller area, freeing up most of the cupboard space.

The expansion bottom piece was created so I could attach two together and have them fit in my cabinet space. You could just print two towers and place them next to each other, or glue them on the horizontal edge. Whatever best fits your scenario.

The tops are the same on both.
