Hiccup and Toothless (How to Train Your Dragon) keychain. You can print it in multi-color without using any other filament. Just change the filament in the layer.

Suggested layer change order: -0mm to 0.6mm Black (base color) -0.6mm to 0.8mm White (skull color) -0.8mm to 1mm Red (tail color)

You can print it 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 in the layer, follow any of these tutorials.
