Well,
I really like the Cubone model @val_142613 and the Ornamental one @NT_284961 but I wanted them to be displayed in the right way. So I designed a quick stand for these model, I guess you can easily use it for different more models like the Mewtwo Ornamental skull.

ORNAMENTAL (https://www.printables.com/de/model/219848-ornamental-cubone-skull-from-pokemon)
The file is about 20 cm high and can easily resized to your needed height.
The bottom is inspired by a Pokeball. I hope you enjoy and happy printing!
edit I just used some PlayDoh for fixing the skulls on the stand*lol*
