3D Marble Maze
thingiverse
This is a standard 3D maze setup. Configure the discs so that the marble can roll through easily!\nDISCLAIMER: You will need to adjust the scale and rotation to avoid having it displayed sideways on your own.\nWhen posting, make sure to export it correctly, as I had trouble with this one initially and would prefer not to redo it.
