An addictive fidget toy based on mechanism in a retractable pen, often called a click mechanism, typically involves a spring, a cam, and a plunger. When the button is pressed, the plunger moves, rotating the cam and extending or retracting the plunger. The spring provides the tension for retraction. When you’re feeling stressed or just need a quick brain break. Click it, pop it, and let that spring-loaded motion melt the tension away. It’s like your stress-busting sidekick

Tips & Tricks

• Apply lubricant grease to the surfaces of the rotor and plunger. Ensuring these surfaces are properly treated is crucial to prevent the mechanism from stuck.
• To improve the rotor’s performance, we can use adaptive layer height to increase the surface smoothness in specific areas.
