I made my prototype out of curly maple and mahogany.
I learned several things after building the first one, like glue up all of the sides in one long piece and then plane and sand to thickness. Also move the dado for the box bottom up to 5/16" from the bottom edge of the sides so that the groove doesn't hit the glue joint for the trim pieces.
Start to finish you should easily complete a couple of boxes in a weekend.
Here is a look at the trim detail on the side of the box. Make sure that you are cutting the trim pieces from the far side of a wide blank for safety because they are pretty thin. You can also see the splines sticking out of the end of the box that I haven't trimmed up yet.
