4 December 2010Sold out 2010 Limited Edition Set of 40. Original Price: AU$350.00 One of these puzzles resold on Haubrich Auction in May 2019 for Euro 210.00…

12 hexagonal sticks & 12 dowels. Six stick-dowel pairs joined to form six elbows. 18 pieces in total.
Aka “The Monster”. The more elbows the harder the puzzle.
Stewart theorised that the maximum number of elbows that can be joined before assembly becomes impossible is half the number of each type of piece, so that’s what Brian has done.
Brian has built the puzzle in the reverse direction to Stewart’s drawings, after all we are downunder. Stewart noted that the lattice structure repeats itself indefinitely in all directions, so it would be possible to make larger assemblies with more and longer sticks and dowels.
Size: Hex pieces are 140mm long.
