I created a 2-inch hitch pin (screw top) for holding hitch accessories, like some sort of insert, not for towing of any kind.
If I post the hitch pin to Makerworld and some idiot decides to tow their motor home with a PLA pin can I be held liable? I am guessing the
license for these models states this?
I will post a warning in my descriptions, but idiots are going to idiot…

Legal Risk Overview
If you clearly label your hitch pin design as “for accessory use only” and not rated for towing, you’re taking the right steps to reduce liability. However, here’s the nuance:
What Helps Protect You
• Clear disclaimers: Label the part as “not for towing,” “for display or accessory use only,” and “not load-bearing.”
• No implied safety claims: Avoid phrases like “strong,” “durable,” or “tested” unless you’ve done certified testing.
• MakerWorld terms: Most platforms include user agreements that place responsibility on the user for how they use shared files.
What Still Carries Risk
• If someone ignores your disclaimer and uses the part for towing, then suffers damage or injury, they could attempt to hold you liable—especially if:
• Your design resembles a real hitch pin closely.
• You used language that could be interpreted as implying strength or suitability.
• You promoted it in contexts that suggest towing use (e.g., showing it installed on a trailer).
While actual legal liability would depend on jurisdiction and specifics, civil claims or platform takedowns are possible if someone misuses your design and blames you.
Best Practices for Protection
• Include a text disclaimer in your MakerWorld listing and on the STL preview image:
“For accessory use only. Not rated for towing or load-bearing applications.”
• Consider adding a non-standard geometry (e.g., slightly oversized or undersized pin diameter) so it won’t fit standard towing receivers.
• Avoid naming it “hitch pin” alone—use something like “decorative receiver pin” or “accessory mount pin.”
Just add a warning.
This model is designed to be used for the sole purpose described.
If you use this model for any other reason, you do so at your own risk and without my approval while acknowledging all risks are your own.
You could also add…
Please, film any stupid undertakings as I like to see idiots.
Remember, Microsoft doesn’t warrant the ?ms Word is a word processor!
I’d embed a warning in the part itself too. “Not for towing” or something obvious. The other advice about warnings and anything that could make the model unsuitable for actual towing is also very good.
But liability issues are real and all it takes is a sympathetic jury to clean your clock.
There’s many dangerous models here though and few seem to care. In today’s environment even marginally realistic guns can get you killed. Those stupid “sunglasses” that are just grids can cause an array of burn marks on retinas and ruin eyesight yet are featured on the main MW pages. All the “herb” grinders that can shed plastic into things people may smoke, the food items that can shed tiny filaments into foods, and so on.
People that visit here to select things to print really need to always think about safety issues because we have thousands of people making all kinds of products with what seems like little to no safety considerations. Many of the models here would make national news for safety recalls if they were actual products.
And there is always the option to not post the model if you think the safety aspects might cause liability or you just don’t want to harm people. There’s plenty of stuff I make for myself that won’t ever be posted here because of possible safety issues.
edit. Didn’t see that my 2 very distinguished collogues had already given the answer in a much better way. I differ to the two gentleman.
Misread that, my mistake.
Some might like a jury of peers to clean a “clock”… Sounds interesting…
Hmm, Federal Cases or Local State.
Really either will do at this point.
Talking strictly about disclaimers for prints of course. Certainly not other things…
I think this is the way to go. When in doubt, don’t post. I would just be too worried about someone misusing your model. Folks often don’t read the description at all so there’s no way to be sure they’d see your warnings.
Might be best not to post, it’s super easy to create and I don’t want to risk getting sued.
Is that a 3-d printed helmet?
can you DM me the link to this model, I really like it and can’t find it. Many people think that bicycle helmets in Canada undergo some kind of advanced or “magic” safety testing. This isn’t true. A helmet like this would still pass the official safety standards—and with plenty of margin to spare.
Just sent it to you.
A device that claims to be a safety device and doesn’t function as a safety device is inexcusable – big red line – nobody likes that – do not make those kind of claims, you’ll get caught up in having to prove not malicious behavior which is difficult.
Everything else is rather open to interpretation imo, disclaimers or not. Label it a “novelty” if you want a well-trodden path of absolving responsibility for user error
Maybe call it hitch accessory hook, or something that’s more accurate and speficic, instead of hitch pin that can be interpreted incorrecty.
The photos should only show it holding accessories. The photos can also have text in big enough font warning users not to use it to tow.
Bold and big fonts for the warning in the model description and the print profile.
Or don’t publish at all, which would be my choice if something can be easily misused and cause harm. A motor home detached from the truck amid transportation on the road is dangerous to the public, regardless of who is legally liable.
Sorry for my bad English… engrave in that part a „no towing“ sentence additional to the already mentioned description on your model page
