My favourite electronics distributor published another DIY toy, made out of plywood.
It is kind of a balance game, called "Joy Ball Wizard" where you can move a bearing ball on a movable plate using a joystick.

The project has a german description, made by Jürgen Grzesina, which can be found here:

I've created some 3D parts to avoid that woodwork. The project is published here:

Than I found the "Labyrinth Ball Table" project and I remixed both designs to one. I fully redesigned my whole thing again and used just the plate with the labyrinth from the ball table project.

Have a look at the video:

Credits go to Vincent Lescault (trentesous) for the maze design! Thank you very much.
Note: I did not upload the file LB_MAZE_3DP_2.STL, please get it from trentesous project:

Anyway, the file is contained in the my fusion360-file, you can export it from there, too.
