Mobius maze

thingiverse

Randomized maze on [Möbius strip](https://en.wikipedia.org/wiki/M%C3%B6bius_strip). Based on [OpenSCAD 2019.05](http://www.openscad.org/downloads.html). You can set `angle` to `180 * n` in the .scad file. For example, if you set `angle` to `0`, it's just a circular maze. [Clean code](https://github.com/JustinSDK/dotSCAD/blob/master/examples/maze/mobius_maze.scad) based on the [dotSCAD](https://github.com/JustinSDK/dotSCAD) library. include <hull_polyline3d.scad>; include <rotate_p.scad>; include <square_maze.scad>; rows = 48; columns = 8; block_width = 2; wall_thickness = 1; angle = 180; // $fn = 24; leng = rows * block_width; radius = 0.5 * leng / PI; a_step = 360 / leng; blocks = go_maze( 1, 1, // starting point starting_maze(rows, columns), rows, columns, y_circular = true ); walls = maze_walls(blocks, rows, columns, block_width, bottom_border = false); for(wall_pts = y_twist(walls, angle, rows, columns, block_width)) { z_rotated = [for(pt = wall_pts) rotate_p([radius + pt[0], 0, pt[2]], a_step * pt[1])]; hull_polyline3d(z_rotated, wall_thickness); }
