Aspiring video game developer and Thingiverse user ClassyGoat was inspired by some fan art to design and 3D print some Pokemon themed Russian nesting dolls. ClassyGoat used the Squirtle, Wartortle, and Blastoise evolution chain and was able to find some 3D models that were pulled directly from the video games. He simply tweaked the models in 3ds Max 2016 to cut them in half and resize them a bit so the smaller model would fit inside.
