Clueless Maze Toy

I developed this as a sideline while modelling a different type of maze that I had invented a long time ago. The maze uses a 3/16 inch (~4.8mm) diameter steel ball bearing which is inserted after printing the maze. Once closed in, the ball is trapped in the maze but can be manipulated by tilting or with a fingernail or a toothpick. The blocks in the maze are slightly different shapes which allow the ball to pass or prevent it from passing. As a result, the course of the maze is difficult to
