I printed so many of these last week to take to school for my students to use during class and exams. They are truly silent and so fun. I put the magnets in most to attract, but accidentally put one to repel, and they both work. Repel makes the octagons line up, but both work equally well to fidget with.

All of these designs are fantastic, but this one might be my favorite to spin. Polaris is my daughter's ring of choice as well. Many of her friends at school have gotten them as gifts!
