This modular container has adjustable units and adjustable height for each unit. Currently, in the customizer, there are cube and honeycomb shape for choice, and two ways to generate: set the sequence and height values as a list, or generate randomly based on rules.

I printed 9x9 and 1x3 boxes as tool box. It can also generate single unit or amounts of units(something with very dense grids) that can serve different purposes.
