While I agree that people need to look at 3D printing as it's own thing and not v.01 of a star treck replicator that allows you to avoid shopping for little plastic thing. There are still plenty of little plastic things that cost huge multiples of there mass produced manufactoring costs, aka a little plastic lever used in the trip odomitor of a 20 year old car the first 20 million of them sold out so now it's small batches pluss warehousing and shipping costs which can easily make such things cost 100+$.
