Ice-choked tower, Mondavia, Nanglangka.
I just tossed that foam, one of the corners of the plastic insert underneath, and the cardboard diagonal center. So I just have one plastic corner which stores all of the plastic pieces and leave the gap in the rest of the box for everything else. Board goes on top.
I did the same thing with a heavy heart.
I loved the idea of the custom foam, but it was quickly apparent that it wasn't practical for day-to-day use.
