Cube-Maze

This 9x9x9-3D-maze is a perfect 3D-maze which means that there is only one single path from one point to any other point. It is also a combination of 3 different 9x9-2D-mazes.
The aim of the game is to visit all the cells on the same face using the cross and to do this for each face. It's not difficult but also not too easy!
 

Printing
There are:
- 6 faces (front/back, top/bottom and left/right),
- 12 joints to connect the 6 faces together,
- the cross composed of 6 branches and 
- the cross-connector composed of 2 pieces to connect the 6 branches.
Print one additional cross connector (2 pieces) which will help building the whole cross.

Assembing the cross
- Start by assembling the cross by first gluing the 2 branches of the X-axis on the cross-connector,
- do the same for the Y-axis (perpendicular to the previous one),
- glue the second cross-connector and
- finally glue the 2 last branches of the Z axis.

Assembling the 6 cube-maze
This is the most sensitive part of the assembly, the slightest error in the position of the cross will make the puzzle unplayable.
1) Start placing one branch of the cross at the bottom left of the BOTTOM face.
2) Place and glue the FRONT face using the joints taking care to place a branch of the cross also at the bottom left of this face.
3) Place and glue the LEFT face taking care to place a branch of the cross also at the bottom left of this face.
Place and glue all other faces

Enjoy!
