I made these super easy marble maze fidget toys for the kids. Bubby loves mazes and so it was very fitting. A bigger one might be good once he's older too. I sewed 2 pieces of felt together and then made the maze pattern with marble sewn inside. The pattern really could be anything (as long as it's a possible maze). I obviously kept with the size of the marble, although one part is quite tight (The felt might stretch..). I think it would be a good fidget for other ages and even a good toy for arthritic people.
