Filament guide replacement for Eventorbot direct extruder

The old metal filament guide was badly designed so I used Shmorgans MK7 Type Extruder - Heavy Duty extruder (http://www.thingiverse.com/thing:27284) and build it in my existing direct extruder. I dont like the springloaded filament guides with only one arm and even if this is not made for quick loading it will provide more pressure on the filament itself.

I also turned the motor direction which makes it much more stable and saves material. At the moment the motor hangs in the air which is fine, I might add the roller support later.

One final change will be the shift of the hinge axis directly under the drive gear so that the filament pressure can´t lift the motor up anymore. This one a problem in the first version (http://www.thingiverse.com/thing:172076) and should be substantially reduced by now.
