Custom 3D Maze

thingiverse

This is a customizer for a 3D maze. Put a marble/BB/small ball/(lab rat?) in one end and rotate the maze until it comes out the other end. It is a remix of JustinSDK's "Maze generator, pure OpenSCAD" to make it 3D. Make the block width equal to the diameter of the ball plus some clearance, e.g. for a marble 16mm diameter + 3 mm clearance =19mm. If you want to be able to see the ball as it moves through the maze, use a peephole, or print with transparent plastic. Change the seed value to get a different randomization. Note - do not use supports on the inside of the maze - they will be impossible to get out (unless you have a multi-material printer and use dissolvable supports). You can rotate 45 degrees in your slicer and add supports on the outside. Or print with no rotation if your 3D printer can do bridging. If you make the maze too large, for some reason, there will no be no error message, but the peepholes will be extensions instead of holes. Change to circle peepholes, or don't use peepholes.
