You can print a Najimi Osana keychain or stamp from the anime (Komi San) in multi-color without using any additional layers. Just change the filament in the layer.

I recommend using a layer height of 0.2. You can set it lower than 0.2, but I don't recommend setting it higher because colors will be lost.

Suggested layer switching order: -0mm to 0.6mm White (Base color) -0.6mm to 0.8mm Beige/Skin color (Face color) -0.8mm to 1mm Black (Eye and contour color) -1mm to 1.2mm Burgundy (Dark tongue color) -1.2mm to 1.4mm Salmon (Tongue and cheek color) -1.4mm to 1.6mm Light pink (Hair shadow color on face) -1.6mm to 1.8mm Purple (Hair shadow color) -1.8mm to 2mm Rosewood (Hair color) -2mm to 2.2mm White (Hair highlights)

You can do this with any colors you like or have, simply by changing the filament in the layer. I recommend using PLA and a 0.4 nozzle or smaller for greater detail. If you don't know how to change the color, For layering, follow any of these tutorials.

Since it's embossed, you can print it in one color and use it as a stamp for clay or modeling clay.

Recommendation: -If you scale it or change the layer size, double-check the filament change. -Nozzle 0.4 or lower. -At least 8 colors (Suggestion) / You can also paint it. -Suggested material: PLA and/or PETG.
