These bearings are great! Foolproof design and using the lightning infill is very clever. I would not have thought it would work well but they certainly do.
I agree with the statement in the main picture for these bad boys. They are the best bearings on Maker World.
The other kind on here with cylinders or balls, just aren't worth it. Not with how well these work. All while being so much more simpler.
I've printed them on my P1S, A1 and Ender 3 S1 Pro. Everytime they come out great and work as I need them to. I do add a touch of low viscosity oil. Makes them a bit smoother. Hopefully just makes them last much longer.
P.S. No offense to any of the cats that made any fancy bearings on here. Just, sometimes simpler is better.
