As someone who once printed things as a business and still has 4 printers on a shelf, I want to offer a counterpoint. The vast majority of people do not need a 3d printer for more than the occasional part/bit that they can't get easily at a store. And by "occasional" I mean "a few times a year". It's simply not worth the cost, learning curve, hassle, etc. for an inferior part at the end of the day in comparison to an injection molded piece off Amazon/eBay or paying someone else a nominal fee to print it for you. I'd be willing to bet that probably 90% of people who are initially enthusiastic about printing and buy a printer only use it once a month or less a year later. In other words, you're in the minority here. It's also worth noting that none of the things you mentioned actually require a 3d printer. Your router mounting bracket could have been made the same way I made mine - a piece of acrylic (or wood), 2 minutes of sawing, and 5 minutes of drilling & tapping for a smoother surface and better strength than what you printed. Your bike bracket could have been made with some aluminum, a band saw, and some files (or just "good enough" formed with some epoxy putty or hot water moldable plastic). Etc. What I'm trying to say is that 3d printing enthusiasts tend to be overly positive about the technology and fall into the "when you have a hammer, everything looks like a nail" trap. It's a great technology, but it's not for everyone (or even most people) and it's got a lot of limitations. I always urge people who are considering buying a printer to strongly consider their actual use cases and needs beyond the cool factor.
