About this 3D model

A little tilt maze I designed in OpenSCAD. The point of it is to put the ball in one side, and by only tiltting the maze to get it out the labyrinth. It also has the letters "3D" on it. It doesn't come with a cover (so you can see where the ball is), but below is the code I used to make it, so you can edit that. maze=[[1,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],[1,0,1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,0,0,0,0,0,0,1,1],[1,0,0,0,0,0,1,1,0,1,1,0,0,0,0,1,1,0,1,0,1,1,1,1,1],[1,1,1,1,1,0,1,1,0,1,1,0,1,1,1,0,1,0,1,0,1,0,0,0,1],[1,1,1,1,1,0,1,1,0,1,1,0,1,1,1,0,1,0,1,0,1,0,1,0,1],[1,0,0,0,0,0,1,1,0,1,1,0,1,1,1,0,0,0,1,0,1,0,1,0,1],[1,1,1,1,1,0,1,1,0,1,1,0,1,1,1,0,1,1,0,0,1,0,1,0,1],[1,1,1,1,1,0,1,1,0,1,1,0,1,1,1,0,1,1,0,1,1,0,1,0,1],[1,0,0,0,0,0,1,1,0,1,1,0,0,0,0,1,1,1,0,0,0,0,1,0,1],[1,0,1,1,1,1,1,1,0,1,1,1,1,1,0,1,1,1,1,1,0,1,1,1,1],[1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,1,1,1,1],[1,1,0,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,1],[1,1,0,1,0,1,0,1,0,1,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1],[1,1,0,0,0,1,0,0,0,1,1,1,1,1,1,1,1,1,1,1,0,1,1,0,1],[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,1],[1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1],[1,0,0,0,0,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],[1,0,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],[1,1,1,1,1,1,1,1,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1],[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,1]]; difference(){ translate([0,0,-4])cube([80,100,8]); for (xpos=[0:20], ypos = [0:24]) if (maze[xpos][ypos]==0)translate([xpos*4, ypos*4, 0]) cube([4.001, 4, 4]); } translate([110,0,0])sphere(1.8,$fn=100);
