Hi all! Thanks for all the replies ! I played a little bit with Tinkercad and we’re close enough. The only part needing perfection is the little lock (le opening piece needs manual help to open), but that’s the same thing for the original one. An other solution is indeed passing through a chinese marketplace if the wait is not long enough and the CO2 impact is not important for you. The printer was a little difficult to have it printed, and I had to print it on the side.
