Impossible Dove Tail Puzzle

A remixed version of jcheger's Impossible Dove Tail Cube. I included a spot for a ball to go in order to make it seem more impossible for the ones who don't know it's there. I got the idea for the ball from a video I saw with a ball bearing and a tiny magnet on either end of the holes (maybe an idea for an add-on). https://youtu.be/xp-PENvptu0
