3D model of magnets orientation, where you can see how magnets need to be inserted. On models there is L and R tags.
Left tag can be magnets with South pole on top, but it is not importatnt. (Until you flipp it later or you use your parts with parts of somebody else who chosed oposite orientation)

The author marked this model as their own original creation.
