5th Gen Clearance Bar

Why? ... Because clicking scares me. Anyone who bought the 5th gen right as it came out, knows well that it had "a few" issues. Now it works great, but i still get scared at the sound of any clicking.
As the extruder moves left the feed tube will come into contact with the left rail wall, which is okay, but as it keeps going left, the feed tube would often fall below the rail making a click type noise. This clearance bar will allow the feed tube to just slide along the flat surface and prevent the it from ever falling below the rail.
