3d Printing Saves Money!
Many people still consider the 3d printer to be just a quirky toy. I think until I got one I pretty much thought the same.
Sure, I had ideas of what I'd do with one but it was also figurine oriented thoughts. I never looked at any of the sites dedicated to models until recently... I could not be amazed by how many useless things I could suddenly that would or already had nickel and dimed my wallet.
What's more it's plain to see that the average creator has far more vision and skill than most company out there pushing sub par junk. When you don't have to choose one designand ram it down the public's throat due to mass production, you can suddenly explore designs to anyone's taste or purpose. It's amazing.
