NOTE: Keep this structure assembled to compare with the next structure.

Finish each layer before starting the next layer. • Complete the unit cell by repeating the first layer (1'). • Carefully disassemble the two remaining structures.

(Layer 0, grey straw spacers, must be assembled first!) Finish each layer before starting the next layer. • Complete the unit cell by repeating the first layer (1', ). • Carefully disassemble this structure.
