Educational Shapes Toy

I saw this idea online but could not find where to download it. So I decided to model it up myself, it was easy enough for me with my limited 3D modeling knowledge. The toy is designed teach the differences between three basic shapes. a circle, a square, and a cross. You rotate part 2 until it can fit into one of the three cutouts of part 1. I sized it to just fit onto the build plate of my Adventurer 5M.
