to be able to lock/unlock this safe, you have to guide a steel ball using a magnetic keyon a track all around the safe itself
then guide the ball in the door to make it possible to move the locks
if the ball falls, because of the shape of the track, you won't be able to put it back on, you will have to restart from the begining (target mark on the middle of the back of the safe)
the one in picture here is a "debug" version, so not fully closed
video of the door working (would have needed the upscale since everything is pretty hard to move here) : https://www.youtube.com/watch?v=wwrGLRyzSf0
you need an 8mm steel ball and 10mm diameter neodymium magnet
it might be good to scale the model up a little bit (like 105%) and use a negativ horizontal compensation since it was modeled without clearences (I prefered to do it this way, because different printers will give different clearence)
orientations to don't need support :
-safe should be with the openning on top
-door with the circle opening for the key on top (it should have 1 filled layer just to help define the circle, remove it after printing)
-other parts have pretty obvious orientation
then to assemble everything :
-push the ball through the hole on one side of the safe openning
-push the magnet inside the key
-slide the knob in the door openning on front
-slide the 2 locks in the door in sync (so turning the know moves both to the same position)
-and use 2 short filament cuts as hinge for the door (openning on the back of the door to access the hinges holes)
