@corndogjax Yes, the walls are as tin as they can practically be made, in order to keep the cost as low as possible, and also to allow the modeler to more easily add an interior if desired. I assume that any modeler tackling a model such as this would be familiar with basic modeling techniques, especially those needed to build a resin craftsman kit.
Every FUD and FXD model I have ordered from Shapeways has shown some tendency to warp. The walls can be straightened in hot tap water, a heat gun, or even a hair dryer. They can then be braced with the addition of styrene, brass, epoxy, or any other practical material - all of which is far less expensive and more durable than the 3D printed material would be.
