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.
