My next project were those bearing that I 3d printed on my Ender 3 Pro. I got some ball bearing from amazon exactly for this purpose. To try and make a working bearing for my other project.
I used what I learned in my last project with the spur gear to make them easily modifiable with the User parameter.
The Fusion360 file contain my user paramerter that are needed to modify it to the right size that you want.

I printed them on a Ender 3 Pro with basic setting nothing fancy as always.
In Cura 4.4
no support / no rim,raft,brim,etc /
They take about 1 hour to print. I was able to print them all at once by manually placing them so that they wouldn't interfere with one another.
