Alcatraz Puzzle

thingiverse

This is the Alcatraz escape puzzle, and solving it poses quite a formidable challenge. Insert a 9 mm ball bearing into the large hole and navigate your way through to the small hole. You can choose to use the solution.png as a guide or tackle it head-on without any aid. Taking a closer look through the windows will greatly enhance your chances of success. If you want to visualize the solution in 3D, load the file solution.scad into OpenSCAD (visit www.openscad.org/downloads.html for more information). Additionally, get the files Chamfer.scad and core.scad into the same directory. However, be prepared for potential difficulties with 3D printing - make sure to disable all support generation to avoid obstructing the tunnels and rendering your puzzle useless. After printing, I found it necessary to sweep the tunnels with a screwdriver to clear some stringing that had occurred. The model was generated using a Java program that produced OpenSCAD code.
