monitor Monitor stand incompatibility

[Tuganerf]

Hi guys,

My current setup takes way too much desk space and I was thinking of stacking my monitors and put my laptop a tray.

I was wondering if any of you have similar setups and if you know of the best way to achieve it as I don't know if the arm measurements are standard.

Feel free to drop any links or tips on how to achieve this.

I photoshopped some images to show what I'm looking for.
