Motorized height adjustable monitor mount.

Hi !

I would like to share my mount, it's not perfect but it works and could give you ideas ! It could be greatly improved but it works for 3 months on two 27 inches monitors with no problems.

What's needed :
- 6mm bold, nuts and washer for fixing monitor arm and sliders
- some M3 screws for the motor,
- 6mm threaded rod
- Motor (http://www.banggood.com/12V-DC-Metal-Gear-Reducer-Motor-High-Torque-DC-Gear-Box-Motor-p-925500.html)
