Color Changing Vortex Fidget

This is a magic vortex fidget print with dual color filament.The outer ring and inner spiral pillar are integrated so it would separate while you are playing it. Designed in Rhino Grasshopper, the spiral is calculated properly .Each slide of the Ring will rotate the inner pillar 180 degree, so it will change into another color of the dual color filament. If you slide it fast enough, the color will change in a blink magically!There are 8 grooves surround the outer ring fitting your finger, you can quickly filp the pillar for the next slide. Printed in single color will not lose the fun as a nice and smooth fidget!!! Feel free to try it out!!!!
