I printed this on the UP quite a while ago, and it worked out very nicely, although it took quite a bit of effort to get the balls freely moving on the outer rings.
This one was printed on the M200.
0.19mm
Normal speed
10% support
No fan
Solid fill
My first try resulted in the balls coming loose from the support when using 20% fan, but without the fan they stuck much better, but was still super easy to get off the bed. In fact the bearing popped off the raft whilst removing from the bed.
Overall print quality was very good, apart from a small seam. And actually runs much smoother than the UP version.
