External Stepper Driver Adapter for Cohesion3D Mini

This adapter goes into a Pololu-Style Stepper Driver Socket and breaks out the STEP, DIRECTION, ENABLE, and GROUND pins to a 3.5mm screw terminal.  This is a great way to go from a A4988 or DRV8825 on-board stepper driver to breakout the signals to use external drivers, for larger motors and more powerful applications.
