Greg's Wade filament alignment fix (1.75mm)

Once I get to the bottom of a roll of filament i can't print for more than an hour without it jamming as the end of the roll has a tight coil on the filament and this kept causing the extruder to jam. So i designed this quick fix.

It makes sure that the filament going into the extruder is nice and strait. Since I've had this on I've not had a single print jam!

I'm using a Robo3D printer, as far as i know the Greg's wade on there is the same as any other but let me know if I'm wrong.
