I have Anet E12. It is able to print big parts and works very well for me and I use it a lot. I used it to print some replacement parts for my old car (like inside the cabin door unlock part) and replacement parts for children toys, replacement parts around the house (like chair supports). I find a lot of parts on thingiverse. I just dovnload and print them (check out replacement parts for cars, it's amazing). The parts that I don't find online I drow by myself in "fusion 360" 3D sw.
