About this 3D model

You can create a maze with simple numbers: 1 = left, 2 = top, 4 = right, 8 = bottom, If you want to create a full closed tile its: 1+2+4+8 = 15 Bottom and Left Corner is 1 + 8 = 9 = 09 Openscad needs a simple to parse string, so you had to write numbers with 2 digets ("09"). A new line is startet with "br" for break. Every Line had to be in the same length! Be sure to end your string with a br! a simple box is: mazestring="03,06,br,09,12,br"; Every Tile has its own walls.so if you make a [4,1] there is one big wall with double wall thickness between the tiles. with [0,1] you make a wall with normal wallthickness. (You can see the effect in my testmaze in the top left corner. The straight wall at second Position to the bottom has a little edge in the middle. this is because i switched between a richt wall in first osition to left wall in second position) Inspired by http://www.thingiverse.com/thing:24604 But not a real derivate.
