A little experimentation with flexible fabric so far has led me to this design.
Initially, I just wanted to make a flexible brick, one made from clay.
But in the end he was transformed into a brick from a toy construction set.
I took as a basis the principle of a flexible bone that I had made earlier.
I managed to divide it into 4 parts.
And then I changed the design, made the fabric based on the principle of flexible fabric.
This version already consisted of 8 parts. // just 1 byte π
The holes at the bottom are not for beauty, they are functional, you can connect bricks if desired.
