SNS pneumatic quick-connect fitting clip (for air hose outer diameter 12mm)

Model name: SNS Pneumatic Connector Anti-Loosening Retaining Clip (for quick connectors with 12mm outer diameter air hose) Model introduction: Have you ever encountered the problem of SNS (or similar quick-connect) pneumatic connectors accidentally coming loose in tight spaces due to pressure, bending, or vibration, leading to air leakage or even equipment downtime Dedicated retaining clips are almost impossible to find online, so I designed this 3D Printed friendly anti-loosening clip This model is specifically designed for common SNS pneumatic connectors with an outer diameter of approximately 12mm (other sizes can be made and shared based on comments and user needs) It firmly grips the connector body and the air hose connection point with claws on both sides, effectively preventing the interface from loosening due to external pressure or bending Simple structure, easy to install, no super glue or tools required, locks with one press Features: ✅ Compatible with mainstream SNS quick-connect pneumatic connectors (it is recommended to measure your connector size with calipers before printing) ✅ Double-sided elastic clip design, with moderate clamping force that will not damage the connector ✅ Lightweight hollow structure, saves filament, and prints quickly ✅ No supports needed, easily printable with FDM or resin 3D printers ✅ Open-source parametric design (STEP file included for easy modification) Usage recommendations: - Recommended for printing with materials that have certain toughness, such as PLA+ or PETG - If the connector size differs slightly, fine-tuning can be done by adjusting key parameters in the model (such as the inner groove width) - When installing, align with the base of the connector, and gently press the clips on both sides to snap it in Acknowledgments and open source: This design originated from actual engineering pain points and is now open-sourced and shared, hoping to help makers and engineers who are also troubled by "not being able to find accessories" Feedback and improvement suggestions are welcome, and you are encouraged to create derivative works based on this model (please retain the original author's information) Tip: Different brands of SNS connectors may have slightly different sizes, please measure before printing If needed, I can also provide versions in other sizes
