--------------------------------------------------------------------

This is my design of the Y axis idler for prusa i3 steel (leonardo).

The part in combination with the smaller bearings (2x F686-ZZ) corrects the geometrical failure in original i3 steel part.
Belt will run perfectly horizontal and parallel (with standard 20tooth GT2 pulley).
