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.

Notes:

These are the perfect size to hold the largest glass bowl sitting on top if its cap/top. If you want a little extra space to allow for cracks in the tops, which lets face it, happens a lot, then print this at 104%, like I did.

There is enough height so that when all size Pyrex are nested together, you can still fit them underneath and pull them out.
