Here's a ~6" tall hollow rabbit being printed in roughly 7 hours. 3D printers are still just useless and awful. The promise is clear if they ever improve but for now, especially the cheaper home variety, they just don't do anything useful.
We use a cheap 3D printer weekly to make little fixtures, brackets and mounts for robots. These we use for months or years. They are also incredibly great for prototyping: print the doohickey in crappy plastic, check it fits together right, then get it made for real. It's amazing how helpful it is to have a model in your hand for debugging before spending a fortune.
It is definitely not ready for my Nana to print out a new frame for her eyeglasses after she accidentally sits on them. But it will be one day.
