Prusa IGUS RJMP 01 08 Holder
thingiverse
The budget LM8UU bearings on my printer left much to be desired, so I dismantled it and opted for an upgrade with IGUS RJMP-01-08 bearings. These are for the Y-Axis and are derived from jonaskuehling's excellent LM8UU Holder design. To enhance printability with PLA, I modified wall thickness and form. After a month of usage, I haven't encountered any issues. For assembly, you will need 25mm M3 screws (possibly 20mm as well), a nut, and the necessary hardware to secure the holder onto your Y-plate - standard Prusa holes should fit perfectly.
