How do 3/4 of my points presume an industrial setting? (1) Specifically says otherwise, and why would quickly getting something in hand have anything to do with your setting? I suppose (2) varies from person to person, but I've definitely done a heck of a lot of hardware browsing where I ended up with some crappy part from china that was the only thing they had that fit what I wanted. And then it broke, and then I went back and returned it, etc., etc., etc. There is something to be said about designing your hardware to fit your job, not the other way around. (3) Also doesn't presume anything. Yes, most people do not have CNC machines (although I know several who do), but you might surprised how many people have wood/metal shops in their garages or basements. One of the other comments on this very story has someone talking about how having a buddy with a metal shop and a dump is just as good a FDM machine. Again, (4) has absolutely nothing to do with setting. How does being able to cheaply whip off multiple variations of a model having anything to do with industry? Aside from the fact that such methods are often used in industry, because it's a smarter way to do things. Most home-hacking happens one part at a time for exactly the reason I mention.
