About this 3D model

This is the final part of the Quick Fit Extruder being the latch and fixed end for my Dove-tail carriage http://www.thingiverse.com/thing:31322 to take my modified Gregs extruder http://www.thingiverse.com/thing:30951. The extruder can be removed by loosening the 4mm thumb screw and rotating the top of the latch to allow the extruder to be lifted clear nose first.
