On my print for the base I only used infill on the the section near the plate so the bridging would have a surface to lay on. For the sides i used no infill to speed up print and 2 wall the window cuts will add some rigid connections for the inner and outer walls.
On the plate inserts i printed them with enough bottom layers to prevent the need for bridging.
if anyone wants a more accurate layout for the colors i was recently shown this page.
