This article reminds me of another I read first here, 'Reality Has A Surprising Amount of Detail' by John Salvatier. At first blush 3D printing seems easy, but especially with smaller parts that might go through many duty cycles it's anything but. I'm going to have to do more than skim this, I think this one is worth multiple reads over many days to really absorb the densely packed information.
Thanks to the author for being willing to put so much of their hard-earned experience into a resource for the rest of us.
