This step washer centers the connecting screw in the hole of the magnet.  I used an M3x12 button head screw. The assembly connects one rail car with another.  It has been printed with 5 perimeters in PLA.   It was designed in OpenScad.

It was used in my make of @danielschweinert's James Toy train Thomas.
