I redesigned the top bearing to use a parametric bearing that I looked at and made a test bearing of. The design fits the current ART4 parts with extra nuts and bots (8) to hold the bearing together.
I hope that you like it.
can you share the design file?, I’m having some issue with the original ball bearing and I would like to know how you’ve modified that, I don’t understand from you photos if you have placed a modified piece on the existing one or if you have replaced completely the original one with your version.
Thank you so much.
