About this 3D model

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
