Lulzbot TAZ 3mm Filament Straightner

Those small spools from some sellers on Amazon are very small and put a very tight curl in the filament that gets worse as you use the spool. This makes the feeder tube want to curl around the frame and has caused issued with prints occasionally.
This thing will fix that problem by straightening the filament as it enters the feeder tube. Adds a bit of drag to the filament but the extruder does not seem to care.
Should be adaptable to other printers.
