I tried my hand at a articulated multicolor Gyarados. Please note that my test print is printed at a layer height of 0.24mm and might look a bit rough :)

There is a 4 colored, a 5 colored version and the raw .stl (here you have to add support and a small discs yourself ) files for a one colored print or non Bambu users.

I reduced the initial layer speed and added small 0.2mm discs to ensure the small "gills" or "lobes" were printed.

If you don't like the colored eyes, you can change the eye color with a few clicks as they are separate parts.

I used PLA+ from Sunlu (yellow, white and red), eSUN PLA+ Light Blue.
