I created my own version of an incubator for Pokemons / Dragonball characters / and many more. 

(Mewtwo is not included)

If you want, you can fill the glass with water and use a pump to let air bubbles rise its an cool effect 

the glas i needed 69mm in diameter and 145mm in length 

its printed without supports

hope you like and print youre own i would like to see pictures of your Prints.
