Lulzbot Mini 1.75mm Filament Extruder Body Mod

I accidentally ordered a roll of Colorfabb nGen 1.75mm filament for my Lulzbot Mini instead of 3mm filament. I tried printing it with no modifications and had mixed luck as many others have reported with various filaments. The problem I consistently had was compressive buckling of the filament inside the extruder body. I tried a few tricks to ease extrusion pressures like raising the extrusion temperature a bit and a few others, but I was still having misprints in bigger parts due to buckling.
