They're copyright claim is dubious for these works, and trademark doesn't grant as many rights as we often think it does ( you can do anything you want with a trademark, as long as you keep it to yourself). | |

| Jan 31, 2019 at 9:17 | comment | added | Trish | @user3352632 ok, revised it a lot. The legal point is still a valid caveat in case someone other than you wants to use this knowledge to make a deliberate breaking part in an object for sale, so it stays in, but I pulled the emphasis from it by putting it to footnotes. The main point now is how to design it to break and where one can tweek to get that done - mainly under the aspects of how to achieve a safe breaking.7 | |

Set it to single wall thickness and 5% infill. Should last you a good 5 minutes if you can get it off the bed without it self destructing. | |

| Jan 30, 2019 at 7:40 | comment | added | user3352632 | Please do not let this thread degenerate into the clarification and discussion of patent issues. It would be a good idea to remove it from your answer. Everyone has something to say about this issue and knows something better than somebody else. What this question is really about is how you can reprint gears with a 3D printer so that they have fractures. The Lego gears were just an example that I found on Google. My target gears are a bit bigger (maybe 1cm more diameter). So please, give concrete suggestions/ideas. Thank you in advance | |

In the States, copyright law (if I'm reading it correctly) says Lego's copyright on their design is good through then end of 2047. It is far from expired. Lego goes after infringement as well. | |
