Z-Crank with Bearing

Zaggo's Z-crank is great: http://www.thingiverse.com/thing:975

Zaggo's handle is a nice addition to this z-crank:

but i wanted something that turned super smoothly. So take the z-crank and just slap a 608 bearing on the handle. You can turn the crank completely freely without the handle slipping under your fingers.
