Tube Maze - metal

Tube Maze is a mechanical maze. The object is to move the ring around the knotted beams and remove it. Both the flag and the ring are asymmetrical. In the start position, the rings hangs under the flag, but it cannot come off. When the ring makes the right trajectory through the maze, it is turned upside down.Only then, the ring can come off from the flag.

Tube Maze is Oskar's very first 3D-printed puzzle.The original prototype was printed by George Miller on his Dimension machine in 2003, see here. You can buy a 3D-printed plastic version here. This model is the metal version. Next to being metal, the maze has been slightly altered to make it a bit more difficult. Can you spot the differences?
