I'd like to see #29 used in a 3d printer. One spiral driving 3 gears that pull the filament down through the center directly into the hot end. A tiny stepper should do since there is a huge mechanical advantage.

How would you tension the three gears to provide the right amount of pressure across variations in filament diameter?
I wonder how much wear there would be in the spiral sliding across the gear teeth.

Good question. The teeth should be 1/3 apart, so maybe just dig in if the filament is too thick?
There has to be a way, it's just too bougie not to exist.
