Wow! I literally created a new user account here after finding this thread in a Google search! I've never really been into prop-building before, but I recently bought a new Bambu Labs X1C printer and got into 3D printing. And as a long-time science fiction fan, I watched Foundation (just finishing season 2 right around the time I bought the printer). One of my first thoughts was, "Man -- I'd love to try to print out a Prime Radiant model!" So many models are shared around on multiple 3D printing sites, I was surprised to see absolutely nothing from Foundation anyone had shared to print.
What I did find were a number of free downloadable 3D print files to print out a cuboctahedron geometric shape, which is what the Prime Radiant is. I experimented with printing it out using "yellow glass" PLA filament and I got something that looked like you could make a recognizable/passable Prime Radiant with it, after a lot of careful painting of the lattice-work on each panel using black and brass metallic paints. I managed to print it at what I believe is the correct size of the model in the TV series too. But that's as close as I came to it.
The thing is? I believe with some hobby electronics like an Arduino, it might be possible to construct something like this that actually lights up only after it detects movement followed by 3 taps, and THAT would be really cool, IMO. I haven't worked with resin printing before, and maybe that's the key to making a realistic replica like you made here? But it seemed to me it might be possible to build something like this with one panel that swings open to allow putting LED lighting and electronics inside that control it? I don't know. I'm realizing my "big picture" ideas to make one of these far exceed my skill-set.
