Cageless Ball Bearing for 3/16" Balls

Ball bearing without the need for a cage. But it definetely needs a lot of patience to put it together. I will tweak some minor issues to improve print quality.
It's designed to fit 27 balls in three levels. Probably only two levels would also be easier for putting together, but then the bearing would loose its ability to carry also longitudal load.
Update: it took me two prototypes to figure out the new version. All printing issues should be resolved. I also switched to dimensions for M5
