Great stuff, Sarah!
I scratch built a bunch of marker lanterns for cabooses and ends of passenger trains. I thought it would be a pretty simple project to drill out holes on 3 axis in twenty-six tiny metal beads, shape the end of brass screws for the bottoms and add some brass tube and pins on the top and solder it all together. By the time I did all of that I'm sure I could have learned how to make them with 3D printing, such simple shapes, and they'd have printed out very consistent. I wish I would have done it this way.
