Orca 0.4x 2x 624 bearing idler

I found that filament would run off course with the barrel when loading. I wondered if two bearings would help guide the filament to the barrel.

I'm now successfully loading filament while the printer is still printing, which I always struggled with in the past.

This also seems to be grippier, don't ask me why. I'm thinking it might be the 'v' of the bearings digging into the filament slightly.

(Just realised the extruder is starting to look a bit christmas(y) :)
