This was Robert Sandfield's IPP 30 exchange puzzle.  It's sort of a reverse puzzle box - the object is to CLOSE the drawer.

From the Cubic Disection Web site:Lock Box is a sequential discovery puzzle box. Its simple appearance hides a very complex mechanical mechanism that requires multiple discoveries to open. No gravity moves, spinning, tapping, banging or force is necessary or allowed.I think this is one of my best designs to date. Multiple steps and discoveries are required, with knowledge of the mechanism coming in stages until the box finally opens to reveal its prize.
