No 3D printing required! People should get to know their local machine shops better. They can make anything you need. I maintain old steam engines as a hobby, for which parts have not been made for a hundred years or so. We make everything. Anything can be maintained forever if desired.
Everything in this world is more repairable than people think it is. We think things are less repairable than they used to be, but it’s more that we gave up trying, IMHO. My best friend repairs Apple stuff as a hobby and has replaced screens, batteries, cameras, etc in every iPhone and laptop model. People constantly say how modern electronics are unrepairable and that is untrue.
There’s a specific kind of kind of local machine shop called a job shop that will make any one off part for anyone for anything. A lot cheaper than 3D printing, I guarantee.
Sorry to rant, but it’s a peeve of mine that people think the new ways are required to do things we’ve been doing for a hundred years.
