Lego Compatible Roller Bearings

These bearings are ideal for axels that spin really fast or axels that are under a lot of stress. At the start they might not spin too well but the more you use them the looser they get. Also keep in mind that they are really hard to print because of the tight clearances between the bearing parts.Printing:- no supports- seam position random- clean bed for best adhesion- lower speed (about 50mm/s for outer wall should be fine)- flow 0.95- layer height 0.2mm is fine but smaller is betterUsing:The bearing will probably be stuck but it should be pretty easy to get them working. Just rotate the center while holding the edge in place. If you need more torque you can put an axel trough the center with a lever on it. If balls are still stuck you can try putting a bit of pressure on it while rotating the center.If still you can't get it to spin please let me know so I can adjust the clearances. The clearance between the balls and the edges is currently 0.1mm.
