I have a lot of spices, especially these large-sized, can ones. It turns out that most of them are about 70mm in diameter and 155mm tall. I didn't like the models available on the web, so I custom-made one. I am going to make a second one to stack in my counter's corner to make sure it is stable, but it should be rock solid. No supports are needed for this model and it will interlock with a second, stacked unit. If it's a little wobbly, then there's always glue.

Also, hexagons are the best-agons.
