nice…really a cool invention

@Makible already did it.

Why did they go with 3mm sizing? Is anyone using 3mm and 1.75 for dual extrusion as a kind of fine versus coarse fill?

@Chris_Reyes 3mm is not inherently more or less coarse than 1.75, it just requires more pressure to make it extrude. It may ooze/blob a bit more, or start and stop a bit slower, but those are problems that can be addressed in calibration.

They probably went with 3mm because the filament is cheaper.
