Maze Cylinder Box Visible or Hidden

Another maze box.
Remixed from http://www.thingiverse.com/thing:207662 a great maze and labyrinth box on thingiverse.
Features:
-Combined Visible and Hidden variants.
-Visible option so the maze is on the exterior of the inside cylinder
-Hidden option so the maze is on the interior of the outside cylinder, making it completely hidden until the entire maze is solved!
-Completely customizable in openscad. The maze is specified by an array. Box sizes and thicknesses are parameters that can be changed. The number of "maze nubs" can be changed.

You can download 1, 2 and 3 from https://www.thingiverse.com/thing:207662
I have included maze model #4 STLs. cheer4ftc released the model in his comments.

Fixed issue with Hidden Maze too loose.
