Ketten-Safe Puzzle

Some days ago Youtube offered me a short video on the channel of PuzzleHive0105 with this puzzle. This puzzle seamed to be 3d printed, but because I didn't know the name, I couldn't find it anywhere to print. So I designed it myself ;-)
The goal is, to fit the chain in the box, so that the lid can be closed. It is not very difficult, but if You don't know the solution, You may need some minutes or even give up :-)

Later I found a version on printables, called Chain store, but this version is taller, the box is very thick designed, and the connection for the lid isn't quite correct. Also the sizes of the chain links are a little bit different to my version, and my box is even a bit smaller inside, in comparison to the chain links!
