Very nice bearing, almost no radial or axial movement - shows what real engineering can do!
This is my new favorite bearing for my projects!
M3 bolts fit perfectly without need for nuts
the hole in the bearings if very helpful when it comes to assembly
printed my bearing with PETG, and used a raft which was almost impossible to remove from the object.
I do not think it needs a raft but I used it because sometimes PETG objects are very difficult to remove from the bed.
