About this 3D model

##Number 2 of 5 for [Gyrobot's Extruder Week](http://3dprintboard.com/showthread.php?3038-Single-Dual-and-Quad-Extruder-Week). Like the original, only with a [RichRap Quick-Fit](http://www.thingiverse.com/thing:19590) compatible base. Nice and easy upgrade for flexible printing. [Base Mountable version here.](http://www.thingiverse.com/thing:307142) There is a slot for an M6 captive nut so you can add your own hotend or use the [Recreus](http://www.thingiverse.com/thing:263143) style one. Full filament support after the MK7 gear wheel allows a PTFE tube insert to be added down into the hotend for flexible filament printing. If you want to know how to print with this type of filament, please read the following [article](http://www.recreus.com/content/8-how-to-print-with-filaflex-). http://www.gyrobot.co.uk http://www.facebook.com/gyrobotuk
