    Hi there,

    Does anyone know whether it's possible to 3D print a "magic lock", like a copy of the Burgwächter ME/2? Especially with the possibility to 3D print in metal or titanium, this could be more cost effective (my experience with the Chinese locks was that they're sometimes breaking apart after using them once). Also, printing in tough plastic could be an Airport-Safe alternative to the normal locks. Does anyone have an STL file or an exact plan that shows how these locks work internally (so I could try to reproduce)?

    Thanks for the tag and the recommendation @Peter Rabbit

    3D printing a functioning lock at that size is not going to be more cost effective and is unlikely to even be possible given the tolerances on 3D Printing. It certainly would not be better than a manufactured lock. I've looked at it, and out of plastic, I tried a lock in the same shape at twice the size, and it still didn't work well.

    If you want a quality lock, but a legit berg wacther ME/2 lock. They're available from Steinlock in the US.

    Thank you everyone. I guess it is what it is.

    Would be interesting to see your attempt at a working lock twice the size though :)

    All cinese locks have the same key :)

    This lock uses the numbered pad.

    I bought two of these. One worked great and the other would not turn to lock/unlock. The frozen lock must have some debris from the casting/printing stuck in it. Perhaps there needs to be a slightly larger space in the design to allow the lock portion to turn freely? Just guessing, but a fantastic idea.

    Has it been replaced under warranty?

    I used the Shapeways specs ;)
    thank you for your advice, I do it now
