In this video, the creator used two of the following motor: https://www.amazon.com/gp/product/B072L1766N/ref=oh_aui_detailpage_o05_s02?ie=UTF8&psc=1
The specs of this motor are:
Rated Torque: 3kg-cm / 2.6lb.in; Stall torque: 11kg-cm / 9.5lb.in
The desk was still really slow to raise and very noisy.
Guessing I would need two motors with at least double the amount of rated torque?
