Chain Coupling Link – Heavy Duty Connector

This Chain Coupling Link is a connector designed to securely join two chains or ropes, creating a strong and reliable connection for tension or towing applications. The model was developed with load-bearing use in mind.

The main version uses an H6 Allen key for assembly.

I have also included a miniature 8 mm version (H2 Allen key) for simpler applications. Despite its smaller size, it was able to tow a vehicle with another one when printed in PET-GF. You can check the video demonstration.

Ideal for uses such as:

🔧 Rope extension
🚗 Light towing tests
🏕 Outdoor and camping setups
🛠 Workshop utility use
🧰 Experimental mechanical projects

Recommended Materials

For best performance and strength:

• PET-CF / PET-GF
• PETG
• Nylon / PA
• ASA

Avoid using PLA for high load applications.
