This version of the LM8UU bearings for the Y-axis (print bed) is modified to fit Prusa MK3.
The differences from the source model (https://www.thingiverse.com/thing:1848700) are:
- This model is cut down in order to pass over the V-cuts in the frame of the MK3.
- Unlike on MK2, the Y-rods holders of MK3 are not obstructing the bearing holders any more, so now you can use the same model for all 3 bearings.
There are 2 variants:
- For a grooved version of the bearings.
- For a smooth (non-grooved) version of the bearings (for DIY PLA printed bearings with a smooth metal tube shell).
Print in PETG or ABS using 6 perimeter shell.
Use M3x16 screws with hex socket drive. Longer ones will be hitting the V-cuts on the frame, and the shorter ones will not provide enough grip. No nuts required.
NOTE: The photo shows my custom LM8UU PLA core bearings (https://www.thingiverse.com/thing:2202854 with 8.15/13.22 mm diameter and 10 teeth) in 15mm/1mm aluminum tube shell.
