Copyright and reporting illegal content

Last updated 29 September 2026

3D Thing stores models for designers and shows them to the people they share links with. We do not choose or review that content, but we act on reports. This page covers copyright claims under the US Digital Millennium Copyright Act, reports of illegal content under the EU Digital Services Act and the UK Online Safety Act, and complaints under India's Copyright Act and Information Technology Rules. One report is enough; we apply whichever law fits.

If a child is in danger or somebody is at risk of serious harm, contact the police first. You can report child sexual abuse material to the NCMEC CyberTipline (United States), the Internet Watch Foundation (United Kingdom) or your national hotline, as well as to us.

What to send

Email [Copyright and takedown email address] with:

1. Where it is: the exact link (for example 3dthing.in/s/... or the editor address with ?share=). Without it we cannot find the content.
2. What is wrong with it: for copyright, the work you own that it copies (a link or description is fine); for anything else, why you believe it is illegal and, if you know, which law it breaks.
3. Who you are: your name, email address, postal address and phone number, and if you act for someone else, who. (If you are reporting child sexual abuse material you may leave your name out.)
4. This statement, for copyright claims: "I have a good faith belief that use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law. The information in this notice is accurate, and under penalty of perjury, I am the owner, or authorized to act on behalf of the owner, of an exclusive right that is allegedly infringed."
5. For other reports: a statement that you believe in good faith that the information in your report is accurate and complete.
6. Your signature: typing your full name at the end is enough.

You can write in English. Knowingly making a false claim can make you liable for the other side's costs and losses (for example under 17 U.S.C. 512(f)). We may ignore reports that are clearly unfounded or abusive.

Our designated copyright agent

For notices under the DMCA, our agent registered with the US Copyright Office is:

• [DMCA designated agent: name or role], [Registered legal name of the company that runs 3D Thing]
• [DMCA agent postal address]
• Phone [DMCA agent phone number], email [DMCA agent email address]
• Copyright Office designation [Copyright Office designation number (after registering at dmca.copyright.gov)]

What happens next

1. We confirm that we received your report, by email.
2. A person looks at it, promptly and carefully. If it is incomplete we tell you what is missing.
3. If the report is valid we disable the link or remove the content, and we may suspend the account.
4. We tell the uploader what we did, why, which law or term it was based on, and how to challenge it. For a copyright claim we pass on your notice, including your name and contact details, so they can respond to you.
5. We tell you what we decided.

Either side can ask us to look at a decision again by replying to our email; a different person reviews it where we can. This does not stop anyone going to court.

If your content was removed by mistake

If we removed your content after a copyright claim and you believe it was a mistake or you have the right to use it, send a counter-notice to [Copyright and takedown email address] with:

1. the link or name of the content that was removed;
2. this statement: "I swear, under penalty of perjury, that I have a good faith belief that the material was removed or disabled as a result of mistake or misidentification of the material to be removed or disabled.";
3. your name, address and phone number, and a statement that you consent to the jurisdiction of the US federal district court for your address (or, if you are outside the United States, any judicial district in which we may be found), and that you will accept service of process from the person who made the claim or their agent;
4. your signature (your typed full name).

We forward it to the person who made the claim. Under US law we restore the content between 10 and 14 business days later, unless they tell us they have gone to court.

Repeat infringers

We close the accounts of people who repeatedly upload content that infringes copyright, when we receive valid notices about them.

India

A copyright owner may send a written complaint under section 52(1)(c) of the Copyright Act, 1957 and rule 75 of the Copyright Rules, 2013. Include the details above, evidence that you own the work or hold an exclusive licence to it, the name of the person who uploaded the copy if you know it, and an undertaking that you will file an infringement suit in a competent court and send us its order within 21 days. We disable access to the content within 36 hours of a complete complaint and keep it disabled for 21 days; if no court order arrives in that time, we may restore it.

Any other complaint about content, or about how we handled a report, can go to our Grievance Officer, [Name of the Grievance Officer (India)], at [Grievance Officer email address] or [Postal address for grievances (can be the registered office)]. We acknowledge complaints within 24 hours and resolve them within the times set by the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021. Complaints about content showing a person in a sexual act, nudity or a morphed or impersonated image of them are handled first and fastest.
