So, I just got most of this built and finished for a Game I'm running tomorrow.
the Walls, Command Centre, and Mech bay are all 3-d Printed. The board is hexed with 1.75-inch hexes. The Base...(Base ?) is CNC Milled Styrofoam.
I will have more boards (currently drying the water effects on some) , and I will take photos tomorrow of the whole she-bang!
