Rules, reports and takedowns

The full rules are in the Community Guidelines and the Terms of Service. This page explains how they work in practice.

The rules in brief#

• Only share what you have the right to share, and respect the license of anything you build on.
• Be decent. No harassment, hate, threats or personal attacks.
• No spam, misleading listings, or fake ratings and reviews.
• Mark adult content 18+: adult content, firearms and firearm parts, and graphic content must be marked. See Age and 18+ content.
• Nothing illegal: see the Community Guidelines for what isn't allowed at all, including explosives.
• Upload real, working files with honest descriptions.

Reporting#

Use Report on a model, comment, profile, print post or print profile. Choose a reason:

• Spam or misleading
• Copyright infringement
• Inappropriate content
• Should be marked 18+
• Broken or corrupted file
• Other

Add a short explanation if it helps. Reports go to our moderators and are private; the person you report isn't told who reported them.

For copyright problems, a report flags it to us. A formal DMCA notice is the legal route, and you don't need an account for it. See Copyright takedowns.

What moderators can do#

Depending on what happened, moderators can:

• dismiss a report that doesn't break the rules;
• remove a model, comment or post;
• block uploads or ban commenting for a set number of days;
• suspend an account for a set time or indefinitely. A suspended account can't sign in and sees the reason.

Creators can also hide prints and print profiles on their own models.

If you think a decision about your account or content was wrong, email contact@communitycad.dev and we'll look again.

Copyright takedowns#

If something on CommunityCAD infringes your copyright, send a takedown notice as described on the DMCA page. We remove the material promptly and notify the uploader, who may send a counter-notice. Accounts that repeatedly infringe are closed.

If we imported your model from GitHub and you'd simply like it gone, you don't need a formal notice. Email us and we'll take it down.

Printing safely#

CommunityCAD shares files made by other people. We don't test or check them. Before you make anything:

• Check the file is for your machine. G-code and other machine files are made for one specific printer or machine. A file made for another one can crash the toolhead, overheat, or damage your machine.
• Check the settings: temperatures, speeds, dimensions and material.
• Watch the start of every job, especially the first layer, and never leave a machine running in a way you wouldn't normally.
• Functional and load-bearing parts (brackets, mounts, anything holding weight or under pressure, anything near heat or electricity) need your own judgement and testing. Ratings and comments are opinions, not certification.
• Follow your machine maker's safety instructions, and have a working smoke detector near your printer.

Ratings, print profiles and "Printed N times" help you judge a model, but they're not a guarantee. You're responsible for what you make and how you use it. See the Terms of Service.
