The aMAZEing Labyrinth (by Ravensburger) is a board game that I've thoroughly enjoyed to this day. It's a game that involves a bit of luck and a bit of strategy while not being overly time consuming. As such, this has provided much entertainment for family and friends. However, tiles have the tendency to go missing. With 3D printing being so readily available, not only are we able to easily replace parts, we can add an aesthetically pleasing 3rd dimension to the game!
Edit 23/01/19: Added T shaped tile.
