Direct Drive Prusa i3 idler remix

for those who tired of replacing 3 times a week cracked idler . I have replaced 10x5x5mm bb with some bigger 10X15X4MM from rc cars TRAXXAS \ HPI rc toy cars, found on ebay. This gives me a more contact sqare with a filament for about 50-60%, and BB was placed little higher making more pressure between gear and bb. Also i have added 10mm m3 screw and some washer from piece of textolite which holds bb in place, and makes this thing sturdy.
