Updated V2 version:

• Less color changes resulting in faster print and less waster
• Face down print orientation for better quality
• Scaled down a bit for 50 mm and 60 mm slot width
• Narrower slot (1 mm instead of 1.5 mm) for better squeeze pressure

Please use the updated printer profile for the V2.

Main filament should be PETG (for strength). The secondary ones can be anything, I used white and black PLA. No worries, they won't separate, all the face components (eyes, whiskers, nose) hold firmly in the main part.

There are 3 colours used in the model: base (face), secondary (nose, whiskers, pupil) and tertiary (iris). You can assign any filament for them.
