Notebook Nations, play trays and insert.

I've made this for Notebook Nations. The idea is to get the game to the table faster; each race has a player tray for buildings and Units.
It does cause a little box lift; mine is slightly more, as some of my prototype prints are slightly thicker than the final design. All the files uploaded are updated to be thinner, which should drop the lid by 5mm compared to the photo here. The oval holes are from the final design; it cuts down print time and filament use.

Each race takes about 46g of filament for its 3 parts.

I'm away till the end of August, so if you have queries or modifications you want, I can't do it till then.
