dots, hexagons or
squares, then build short rods up from that, then place a grid-like
floor, and then build
the model up from that grid. So, the shrinkage-induced stress from the
the floor is allowed to deform those first rods in a gentle manner, so
as to not
overstress the attachment to the platform.
