This is a keychain/necklace based on 2 cat face emojis from the Noto font's emojis. Specifically, "Smiling Cat Face With Heart-Eyes" and "Kissing Cat Face". It requires a printer that supports dual extrusion.
The SVG image files used are under the Apache license, version 2.0.
Print black and white together using both extruders. Print the heart eyes separately--they will be snapped in later (glue optional).
