Nice packing puzzle by Laszlo Molnar described by Brian on his Wood Wonders site:-This was one of two of Laszlo's entries into the IPP Design Competition and a TOP TEN Vote Getter. You know when Laszlo makes designs a packing puzzle that it will be a good one! I think this one has a difficult to find Aha! moment, making it even more satisfying. This puzzle has some rather close tolerances so it may not be for high humidity conditions.

This was very tricky indeed with su...
