Movement Trays for the End of the World

I created some movement trays for the upcoming Armageddon. For starters, I've made these flavors:
* 5x25mm - 0.5" spacing between units.
* 5x32mm - 0.5" spacing between units.
* 5x40mm - 0.5" spacing between units.

I attempted to keep the area in the middle at a minimum to be time/material efficient. The seem very durable even with the holes. The slot of the unit bases are 0.1mm bigger than the intended size, to allow easy insertion removal. I might tweak this value after some more
