I have a flashforge adventurer 3, and love 3D printing. I started out downloading stl files like puzzles and characters from thingiverse too, but then discovered how to design them myself with fusion 360. I now design my own hooks and other things headphone stands and really practical things that need a custom design.
Good luck 3D printing it is harder than it looks and most of all have fun.
