I know we have discussed them in the past, but never really had a topic on them. I see they have come down tons in price and even the cheaper ones seems to be decent such as: Flashforge 3D I have been running into a few pieces for my telescope that no one seems to make and I could easily print...

Amazon has opened a new 3D printing store that allows you to personalize a range of 3D printed products like toys, jewelry and more. Link

So been kinda keeping my eye on this stuff for the last year or so and wonder what your take is? Personally I see nothing wrong with it. In fact I think it's kinda neat and hope it catches on more. Information should never be censored. It's worth watching the whole video.
