Scalar - Strong Jaws System

# Description:
This is an upgrade for the X and Z axis of Scalar 3D printers ( http://www.thingiverse.com/thing:891409 ).
It's called Strong Jaws System as the whole system is based around 2 jaws of 16 bearings each.
It removes the use of smooth rods for the Z Axis, and we re-use the Z axis 3030 extrusion profile instead.
