Heavy Duty Chain Coupling Link - Free 3D Print Model

Description

⚠️ Disclaimer

This model is intended for experimental and educational purposes only. Strength and performance may vary depending on material, print settings, and printer calibration.

The author assumes no responsibility for damage, failure, or misuse. Use at your own risk and avoid safety-critical applications.

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.

looks good, printed with Glass Fiber PETG should be strong!

Nice result!!!! I tested it again today hahaha

@ItalianMutt

I’m loving all these GF filaments, I’m going to have to print this, maybe in some ABS-GF. I thing the GF filaments look the best, have that matte/semigloss finish while maintaining bright colors. how’s it standing up to testing?

DO NOT UNDER ANY CIRCUMSTANCES try and tow or pull significant weight with this . This is a novelty as listed above . Very serious risk and or death happen yearly from things just like this .

There is a disclaimer, just read

@kappanda2009

if only I read this sooner

@user_2743187763

Replying to @3dxav :

I saw it . But it dosn't impart the severity of what can happen . The disclaimer protects you , but not the people who might be maimed or killed . A simple google search and youll.figjre out why this is such a danger.

@aforww

This is absolutely the most ridiculous print I've seen in awhile. Having the picture showing it connected to a car is asinine.

@NotNickMaduro69

so were all smart enough to know not to use this in the way depicted in the first picture right? like theres no reason for me to have to type this out to save a life I know where all super smart and all but uhhhh.... just in case...

great design. and really strong. I think some tweaks can be made to the design to make it print without supports. Thanks!

how is it that strong

Replying to @3dxav :

how is it so strong

@baparks324

would ABS filiment work for loaded applications?

The designer has replied

@3dxav

ABS-GF preferably

Show original

@ItalianMutt

lol, in all seriousness though, how much weight, static load, has this actually been able to take? what about dynamic weight handling? also what about shock load? I’m curious, it seems like it could handle more than I’m thinking. but a car? I mean maybe if no shock and very little dynamic load is applied, get to a static position and with one of the engineering high strength filaments, like PAHT-CF? maybe ABS-GF could handle it. dangerous to play around with though if you don’t know how to be safe about it. I mean did you actually pull a car with this thing? if so that’s wild and cool👌🤯

@ARO.

What no way how much weight is this baby good for with absgf?

The designer has replied

@3dxav

The one tested in the video was printed in ABS-GF, PET-CF and PET-GF, and it actually held up pulling a car haha, but yes, that was with 100% infill. The winner: PET-GF

@user_80163434

would this print good in PEEK ?

Yes, share your results 😎
