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.

A difficult packing puzzle with a particularly nice Aha! moment.  Read Eric's description at https://cubicdissection.com/collections/discontinued-work/products/copy-of-schneider-packing-puzzle
