Filling the printed form, from the back, with plaster makes it rigid for the next step, pouring a case mold. The flimsiness of the printed shell is actually an advantage, the weight of the plaster pushes the mating surfaces down onto the table. The rails impose perfectly square corners and flat sides. I will pour the plaster just to the top of the printed part (not the top of the rails).
