Exactly. There’s a pretty good 3D printer at my local hackspace, and I love it, but it’s utterly inconceivable that I would print enough household stuff to justify it in those terms.
The chosen list demonstrates that point pretty well, actually. (Cellphone accessories? I spent a total of £7 on all my Nexus accessories, and that’s with a second silicon protective case - something I can’t print. Shower head? How often do they replace theirs, weekly? Garlic press and spoon holder - seriously, these are things you would routinely spend a twentieth of your $312 to $1944 on?)
A 3D printer has huge domestic value, but this isn’t it.
Now, printing new starship miniatures for my Full Thrust games, that’s another story…
