Squirrel

Print with 0.4 mm nozzle, 100% infill, first layer height 0.16 mm and the rest of the layers 0.08 mm. Start with brown and at layer 11 change to white. You can use any 2 contrasting colors.

Please note, I use my own recycled filament from PET bottles, so my prints are not so clean, but the result varies from type of filament to transparency of the filament.
