I'm also not sold on household 3D printers. Maintaining and operating a 3D printer would be a hassle. But retail-level printers? That's a no-brainer. I'm certain people would be willing to accept a reasonable mark-up to have things printed for them. I'm seeing hardware stores that prints all the screws and nails on-site (or at a regional distributor, shipped just-in-time) rather than keeping inventory, and "here's a random part that broke on this obsolete product, could you replace it?" services. I'm seeing furniture stores that create made-to-measure furniture of varying dimensions or colours from a standard template to fit your room. Like made-to-measure clothing, as opposed to bespoke (custom furniture) or off-the-rack (furniture store). I'm seeing motorcycle/bike/hockey helmets made to fit a person's head, car seats moulded to a person's backside (currently only an option on super cars like the McLaren F1), and custom orthotics that are cheap enough to become mainstream. I'm seeing mall photo booths that produce figurines instead of photos. But no, I can't see people having a 3D printer in their basement to do any of these things in their house.
