Solving the Labyrinth Gift Box could be really hard and frustrating.
So why not providing the maze as key chain?
You can customize the scad file... using the maze format from
OpenSCAD Maze
thing, when using the MazeKeychain.scad file
Or the maze format from
Alternate Labyrith Gift Box
thing, when using the MazeKeychain_Alternate.scad file
3d model print parameters
Select an already rendered STL file or customize the SCAD file. It takes the same maze format like [OpenSCAD Maze](http://www.thingiverse.com/thing:59...5481) thing. See also Maze generator at http://burningsmell.org/maze.html I printed mine with 0.2mm layer thickness.
