Comment on Ender 3 v3 se y axis bearings loose in carrier.

Epoxy isn’t cheap, unless you have it on-hand already or buy in-bulk. So you can burn ten-or-so-dollars on an epoxy fix that might or might not work as desired, or $40 on an upgrade that should.
That said, are you sure the printer is otherwise in good working order? Have you tried shimming that bearing and running a test print?

Simply let someone reprint that part for you in ASA/ABS?

Resin isn’t that cheap either. Then there’s shipping. That said, if shimming works for test-prints, it may work for this. Personally, I can’t believe there’s not a wedge-centering end-cap or set-screws for dialing in the centering of the bearing just-so, but I’m no expert on this printer.

The bearing is supposed to self center on the shaft with the fitment between the bearing and the shaft. I can’t imagine the pain of trying to manually adjust those very tight tolerance parts for the perfect alignment. Far better to make the housing the bearing goes into correctly from the start.

If the bearing were loose on the shaft, this would be a different conversation entirely.
If adjustment/refinement of the fit in the housing were out of the question, it shouldn’t be made out of plastic, but even in the world of metal-cutting machine tools, adjustment is often neccessary, and if a shim, spacer or set-screw does the job, its what is done.
Meanwhile, my own suggestion was, first, the upgrade kit.
