This fidget toy is the result of experimenting with button designs for a future puzzle. After printing several tests, I realized that people might enjoy the button as a fidget toy.

This is a 2-state click button with an internal mechanism similar to that of a retractable pen. This can be used with or without a long M3 bolt to transfer the click action into a secondary linear or rotary motion. Use the case with holes to see the cam pop in and out of view each click.
