This is a functional 3D printable model of a linear actuator that uses a classic rack-and-pinion mechanism, powered by a widely available 9g servo motor. This actuator is designed to convert rotational motor movement into precise linear (back-and-forth) motion.

• Mechanism: It's perfect for pulling away and the forward movement of a motor (the TT engine)
• Ideal For: Small robotics projects, automated sliding mechanisms, camera sliders, or educational demonstrations of motion conversion.
• Movement: The design allows for a clean, stable extension and retraction.
