I read in a recent newsletter that the NMRA is currently grappling with the issue of how to judge “scratchbuilt” models that were made using parts from a 3D printer.

There is an honesty aspect to it: someone could lie about their source. But you could address that by requiring the modeler to submit their part files as part of the entry process if they claim to have created them. It’s important not so much for the issue itself, but rather as the author of that piece noted, as a measure of how technology is changing the hobby.
