Assembly Instructions (Setup)
Follow the included instruction diagram carefully. Due to the micro size of nanoblocks, precision and patience are key.

- Layer by Layer Construction: Begin with the base of the birthday cake. Build upwards, layer by layer, ensuring each block is firmly connected to the adjacent blocks.
