I just don't think people buy many items that are 3D printable.
Using myself as an example, there's not a single thing in my Amazon purchase history that would be 3D printable.
Even looking around my office for items which might be 3D printable (coffee mugs, drinking glasses, plates,...), I can't imagine it being more efficient or cost effective to 3D print them than simply ordering them off Amazon or running to the store.
I think 3D printing is a great prototyping tool, and I'm sure it'll really speed up some manufacturing processes, but I have trouble seeing it as a break through with directly for consumers.
