Bearing is interference fit when printed at diameter 22.25mm and coins clip into place.
May need to scale up or down if you find your prints shrink from size or a spot of super glue on the bearing if it is too loose. It was perfect a fit on my printer.

Edit 12/2/17 Added 20 Cent Version using 6 Australian 20 Cent pieces.
