This 3D-printable bumper is designed to enhance the physical interface of a standard microswitch, transforming it into a wide-area contact probe. The T-shaped actuator features a curved contact surface and a specialized hexagonal infill pattern near the pivot to provide a balance of structural rigidity, optimized filament usage, and weight reduction.

Key Features

• Wide Contact Surface: The broad, curved design allows for reliable triggering from multiple angles, making it ideal for robot bumpers or broad-range endstops.
• Mechanical Snap-Action: Designed to leverage the internal spring-loaded mechanism of the microswitch for consistent and repeatable activation.
• Modular Compatibility: Specifically shaped to fit common SPDT sub-miniature snap-action switches (like the TS Series or MAC-1210) often found in 3D printers, vacuums, and DIY robotics.
• Integrated Actuator: Replaces or extends standard metal lever arms with a robust plastic interface to prevent damage to sensitive components during high-force collisions.

Applications

• Robotics: Front or side-mounted collision detection for autonomous vehicles.
• 3D Printing: Custom X, Y, or Z-axis endstops for specialized bed leveling or homing routines.
• Industrial Prototyping: Low-cost mechanical sensing for part positioning or safety interlocks.

Technical Specifications

• Switch Type Compatibility: Standard 3-pin microswitch with lever attachment points.
• Mounting: The probe is designed to snap-fit directly onto the switch's existing actuator arm with the correct clearance.

Upcoming Versions

• Upgrades: New upcoming modifications will be uploaded soon.
