G2S Universal Effector Rocker Mount

This is a rocking extruder adapter for my G2S Universal Effector System. The inactive nozzle is lifted a few millimeters above the print to keep it out of the way.

Please note: This is for the *[Enlarged Effector](http://www.thingiverse.com/thing:1430737) only*, it will not fit the smaller one.

Included are a full set of revised extruder adapters, all of which must now mount from the front (using 10mm screws). Unfortunately there will not be room for attached fans on the J-head rocker, you will have to use a single 40mm fan mounted on the spider (revised bracket included). The J-head adapter compensates for the slight (2 degree) tilt of the active nozzle, making it vertical again. (I have not encountered any problems caused by tilting of the nozzles, I removed the J-head tilt because it was practical to do so.)

Using Repetier Firmware, the servo is controlled via "M340" gcode commands:
> M340 P1 S2500 ; select left extruder
> M340 P1 S500 ; select right extr
