@coolspot_825940 the screw holes are loose. It is designed this way so you can swap bearings easier between different spec. This is intentional. It may happen to be loose on both holes. I still have heard of anyone loosing screws. The issue is there, but no reported negative effects. I hope this helps.
@Epicxxxx_327692 Yeah I'm having the same issue - M3 x 10mm screws aren't really gripping into the rear hole, is that expected?
@SGA_59708 Solid input, thank you! The front hole is certainly loose on purpose, becuase it makes sliding in the screws easier for swapping out hardware. The screw retention should be from the back hole, Which I myself find this hole to be loose on few of the holes on every bcar.
Running a compare for the Nexus, and a MK2. These print nicely, and my only concern is the threading of the M3x10 pockets is extremely light. If this comes up for revision, I suggest tightening these to thread on both sides of the bearing.
