Russian 13 interlocked cube designed by Leonid Mochalov
1 December 2002Sold out 2002 Limited Edition Set of 24. Original Price: AU$220.00 Make the 3×3 interlocking cube. The puzzle again comes from the book by Russian…

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.
