Very true; I just made that number up :) But I guess my original point was that it will almost never be cheaper for a consumer to 3D print something than it will be to buy the mass-produced version of that same thing. Unless that thing is covered by an IP license (i.e. a Mario statue or something) in which case there probably is or will be some law against it that just isn't realistic to enforce against individuals.
Just curious: What are you selling?
some odd things, which are not worth mass production:
* http://www.amazon.com/dp/B00QPA3K92 * http://www.amazon.com/dp/B00TTCHHJ2 * http://www.amazon.com/dp/B00RYFM3R2
I have few more ideas in a pipeline. It is not bringing much money, but it does pay for my hobby.
EDIT: I am also open source all of the stuff i am selling (under non-commercial license for obvious reasons) - https://github.com/hippich/stl
Also, not everything can be injection molded.
There is certainly a place for 3D printed products (I know, since I am selling some)
