Multi-Color Printing Tips

Print each component separately to avoid excessive filament purging. The design allows you to assign different colors to the face, ears, snout, tongue, and detail elements, creating an expressive and colorful dog character with minimal waste.

Included 3MF files have pre-configured colors for each part - simply load into your slicer and print!

Assembly

1. Print all components
2. Attach ears using M3x8 screws through the mounting holes
3. Assemble remaining parts (snout, tongue, eyebrow details)
4. Add keychain ring through the top loop
