Bearing block for 8mm (or 5/16") shafts/round rails

NEWS:

Uploaded new version fo the bearing with improved design. Bearing-01-4mm.stl Slightly tighter grip on the rod and using one 2x6x3 mm bearing to the one closest to the mounting face, so that it doesn't build higher than the standard bearing blocks used on most printers. They use the same M3 screws as before, but uses one M2x8 mm screw for the smaller bearing. I'm using these now on my Prusa and it's smooth, quiet and completely slop free.
