Keychain Cow Stardew Valley

Hi, this is a keychain based on a mod of Stardew Valley. I made it for a friend so why don't share?

So, some explanation are required.

I do all the part separatly, but they can't go in each other, even if you scale down the color. I uploaded this part fort the one who want to try to modify this thing.

You need to print the "all.stl" part. But you need to include some pause in your print to change your filament. I made a 2.5 mm base and 0.2 mm for each color. So you need to stop at 2.5,
