The 40mm grid system is “material agnostic” meaning that any material can be used to create parts or components. The system is indifferent, it just cares about dimensions.

These ceramic modules would be great for not just buildings, but furniture and possibly machines (high temperatures, easy to clean etc)
How could other materials be used? Cloth? Rubber? Brass?
