Simple, relatively flat, three-tiered paw print design that can be used for pretty much anything. Especially with magnets for a locker or refrigerator.

If you want it to be two colors without an AMS, use one until around 70% (72% for me exactly). Then watch very closely and when it starts on the third tier, quickly pause the print and switch filament. It may help to start with a darker color on the bottom and a lighter color on top so if you switch them too late it won't show as much. Also, it is better to switch later rather than earlier because an extra layer can hide underneath the rest of the colors while a layer on top of the lower tier sticks out (if switched too early).
