The file 'Printrbot Simple Metal Flexible Filament Extruder Arm (no Supports Needed) 3D Printer Model' is (stl) file type, size is 399.8KB.
This is a remix of the Printrbot Simple Metal Flexible Filament Extruder made by nmackes. This one has been modified to print without support. There are two versions one is normal and the other has an extend lever (pictured) for ease of use.
I have used this along with EricPrints' Printrbot NinjaFlex Pilot Upgrade ( http://www.thingiverse.com/thing:730243 ) to print Ninjaflex and have been successful so far.
