About this 3D model

This is optimized for Filaflex or another flexible filament like Nylon. I also made some modifications to enable the use with the AJGW extruder set. I made this version changing the excellent design by Audran, please checkout the original version at http://www.thingiverse.com/thing:169372 ###Changes in detail: 1. Added filament guide at the extruder top *(AJGW compatibility)* 2. Filled the gap between the tractor screw and the filament hole *(Flexible filament mod)* 3. Down moved the idler axis for better alignment *(AJGW compatibility)* ## Update 01 - 2014-03-01: - Added a flex idler - no escape for the flex filament.
