The “Bunny Only” version of my Chocolate Bunny with Egg model

The 3mf file will load the “hole” and “chocolate bunny” figures, allowing you to print the hole in a separate color if you like for more definition, keeps the hole between the ears from looking too blob-like with no definition. I did print the prototype here though the same color.

The raw file though is with them both combined into a single STL, this is probably a better option if you won't be changing the color of the hole. To see the hole as another color in an example, check out the “with Egg” model linked above.
