No, a belt made of Lego blocks.

At least.

My kid is a Lego freak. Lego sells hundreds of kits, each with custom blocks for the theme of the kit. I can tolerate Lego data blocks, kind of like the Jacquard Loom.

Well, say the size of a red blood cell.

Perhaps with bone. If need be, the cold structure could be prestressed or voids inserted between cells or organs.
