Chain made in one go without mounting - Chaîne fabriquée en une fois sans montage

This is a chain (like a bike chain) which is 3D printed in one go. There is no assembly. To see the details of the making, look at this video : https://www.youtube.com/watch?v=_BYXBs4lo1Q

Only need to remove the supports and unblock the links. All the details in the video. In the video the chain is printed with a scale of 66%. The chain can be printed without raft but it is better if there is one. If you want to make a chain with the number of links that you want, use the file "maillon.step".
