	But power for steppers apparently doesn't work like this - as that indicates 600x geardown if we consider power alone. 140 in lb is 14016 in-oz = 2240 oz in. Then we need 30 geardown for a Nema 17 motor at low speed. That is well doable for a 3D printed geardown.

			:*Note that Nema motors retain good torque at 300 RPM, so we obtain 10 RPM within the good torque regime.
