Ring-Itz are a platform using standard ring sizes to display your favorite 3D models on your fingers!  To be compatible with Ring-Its, simply add a 5x3 mm negative volume cylinder to the bottom of your favorite models before slicing. This is a friction fit onto the ring, so print as many as you'd like to swap depending on your mood! I've prepared a few greatest hits to get you started.
