Robie Robot Battery Cover

Many of you may remember the Robie the Robot coin bank from years ago! Radio Shack sold them at one time but I don't think they are available new any more. I just received a used one as a gift but unfortunately, the battery cover was missing and without it, it doesn't rock side to side very well. I threw together a replacement cover in ThinkerCad and figure I'd share it with everyone in case there are others in the same predicament. It's kind of crude but works fine. Enjoy!
