I tried several times to print the fidget buttons by Iytta but just could not get them to print without fusing together.  My only option was to try making my own.  

This is just the basic button.  I plan to add more designs to the outer ring now that I know that it will spin.

The original size it the size that I needed for the jacket that I need to repair (just under 2 cm or ¾ of an inch).  I love the one that I blew up to 250%.
