Customizable Maze

thingiverse

Create a maze using simple numbers: 1 (left), 2 (top), 4 (right), and 8 (bottom). To create a fully closed tile, use the sum 1+2+4+8=15. A bottom-left corner is represented by 1 + 8 = 9 or 09. OpenScad requires two-digit numbers for parsing, so write your maze in this format and separate lines with "br." Ensure each line has the same length and end with a "br." A simple box maze would be: mazestring="03,06,br,09,12,br". In OpenScad-based mazes, every tile has its own walls. Create a [4,1] tile for one big wall with double thickness between tiles, or use [0,1] for a wall with normal thickness. Observe the effect in testmaze's top-left corner, where a straight wall has a middle edge due to switching between right and left walls. This technique was inspired by http://www.thingiverse.com/thing:24604 but is not a direct derivative. So, imagine your maze, write it in the digit code, print, and play!
