Filament Roller
thingiverse
My previous filament 'roller' didn't really have any rolling action so I did this one. Not sure the reduction in friction really buys me anything but what the heck. Designed for a Prusa I3. Instructions Print the main body and two rollers and two axles. Assemble. If you use PLA you will likely want to heat the top of the main assembly as you put in the rollers. I have not tried ABS but suspect it might allow for a direct insertion without breaking.
