With the assembly just made, place the cylinder of each of the main brackets inside the larger hole of the other.
-
Snap them together
Pull on both brackets to snap them into place of the smaller hole.

Prepare the next link
Take 2 more main brackets, 2 more spacer rings, and 2 more connector brackets. Place a spacer ring between two connector brackets.
-
Assemble the opposite bracket
Assemble the other main bracket with a connector bracket, a spacer, and another connector bracket.

Snap the pair
Snap the assembled main brackets together as before.

Close the loop
Continue this process until just two main brackets are left. Place a spacer between the connector brackets at the join to close the chain.
