Custom 3D Maze

thingiverse

This is a customizer for a 3D maze where you can put a marble, BB, small ball, or even a lab rat at one end and rotate the maze until it comes out the other end. It's actually a remix of JustinSDK's "Maze generator, pure OpenSCAD" to make it three-dimensional. To set the block width equal to the diameter of the ball plus some clearance, use this formula: for example, a marble with 16mm in diameter plus 3 mm of clearance equals 19mm. If you want to see the ball as it moves through the maze, consider adding a peephole or printing with transparent plastic. Remember to change the seed value to get a different randomization. However, note that using supports inside the maze is not recommended - they can be impossible to remove (unless you have a multi-material printer and use dissolvable supports). To work around this issue, try rotating 45 degrees in your slicer and adding supports on the outside of the maze. Alternatively, print without rotation if your 3D printer can handle bridging. Also, keep in mind that if you make the maze too large, there will be no error message, but the peepholes might end up as extensions instead of holes. To avoid this problem, consider switching to circle peepholes or simply omitting them altogether.
