OK, I actually had one ~10 years ago, and never got past making happy meal toys. I'm still fascinated by them, but when I look at what people are doing with them it's ... happy meal toys... I've seen a few ideas here, but am starting this thread in the hopes that I can collect "practical" uses for an FDM printer - particularly from those that already own machine tools. I'm not really interested in 'how' in this thread - just 'what'. I really *do* want a 3D printer (again, sigh) but I can't come up with enough ideas to convince myself that it would be useful in proportion to its modest price.
TIA,
