Summary

I saw a few mazes here and decided to make one. What makes this one diabolical is that you can't see the maze and must solve it blind.

Instructions

Print either full sized or smaller. I built this based on a .25" brass ball as I had a bunch of them leftover from another projects. You could just as easily use a BB with not much difference in play.

I made the lid separate as my machine would not print it without support and support inside the maze would of course be impossible to remove.

If you print in ABS just put a bit of Acetone on the puzzle to glue the lid on. For PLA you need to use glue.

I printed with .2 layer height (.35 nozzle) and 3 perimeters.

If you print with natural ABS (like I did) you can cheat by shining a bright flashlight through from the bottom, then you can see the puzzle.

Don't let it's simplicity fool you, without seeing the maze, this puzzle is very hard to do. It's more difficult if you use the left hole to start than if you use the right hole.
