A model of the Northrop low altitude penetrator alternative to the B-2, to be 3D printed and turned into a kit for Fantastic Plastic is in the very early stages.
And a JPL interstellar precursor spacecraft design with a Pluto orbiter. The goal was to put scientific instruments a full 1,000 astronomical units out using nuclear/electric propulsion. This model is being built with the specific intention of using it to create a set of accurate and consistent diagrams for the next issue of US Spacecraft projects, but I wonder if there might be interest in a physical model of this.
