Replacement feedscrew blocks for mini mills like Bernardo KF10 or Sieg SX1. It enables smooth table running and proper backlash.

Each one acommodate two sealed angular 30/8 bearings (8x22x11mm), M6 washers and M6 40mm screws.

I suggest to print with strong material like ABS with min 25% and 3-4mm walls.

Stock blocks are rubbish. No bearing or bushing :/ No even Oil port.
