my grandson wanted a small display for his lego creations. since his mom needs to pack up the project in her car when they head home, it needed to be easy to take apart and put together.found this design and it worked out great. each shelf is held in place by slipping in between a pair of 3/4” dowels near the top and bottom of each leg. as the legs spread at the bottom and close up at the top, the shelves are pretty much locked in place.had to take out a 2nd mortgage for birch plywood :/
