Lightest fidget spinner bearing remover

Those two rings help you insert and remove bearings from your 3D printed fidget spinner - without any damnage for both.

Why I came up whit this idea
I used to insert and remove bearings from my fidget spinner with a rubber hammer. I then realized that hammering the bearing (and his inner cylinder) damnage the spheres inside the bearings, causing a performance decrease.

How the two rings work
The smaller ring is for inserting bearings in the fidget spinner. It's the same size of the external shell of the bearing, so place on it and use a hammer to push it inside the fidget spinner. In this way you hit only the external shell of the bearing and spheres inside will not be damaged.
The bigger ring is for removing bearings from the fidget spinner. Place it under the baring you want to remove and use the smaller ring and the hammer to push it down from the opposite side of the spinner.

Check pictures if it's not clear. Also, if you speak English, please help me with a better description, because I'm Italian and not so good in English language. :-)
