Print the bearing at 0.1mm. Note that your printer needs to be calibrated perfectly before trying to print this. If some parts of the bearing are fused together, use a flat screw driver on the notch of the offending ball, turn a little to the left, turn a little to the right and so on. For more severe fusions, use a sharp knife. Fusion plastic can be removed with a small metal file, there is just enough space between the bearing balls to do so.

The inside diameter of the bearing is 16mm, so a shaft for the bearing should have a diameter of 15.75mm.
