Cheap 1.75mm dual drive extruder using standard parts. It uses 4 drive gears, two of them function as gears, keeping the other two drive gears in sync. The secondary gear is tilted to adjust the pressure on the filament. Make sure the set screws don't interfere during assembly, shorter set screws may be needed on some of the drive gears.
