Buy at https://puzzleguy.store/products/chained-square-can-you-fit-the-puzzle-into-a-frame Chained Square has 16 squares that are connected with ball chain. This gives it great flexibility, as observed by Peter Knoppers. The goal is to fold a 4x4 square. The puzzle has several other challenges as well. The puzzle is difficult because of the tetrahedral topology of the weave pattern, and the lack of "simple conventional" solutions. The puzzle uses ball chain with 2-mm balls and 1-mm spacing between balls. Eighteen pieces of ball chain with six balls each are needed to weave the pattern. The 3D-printer should be paused at the right height to insert the ball-chain pieces. Copyright (c) 2025, M. Oskar van Deventer.
