VESA Single or Dual Monitor Stand Using 1/2" Metal Conduit

This is a monitor stand set up with mounting holes for VESA 100x100. All holes are sized for M4 bolts and nuts. It can be set up for one or two monitors (or more, technically). I sized the main holes for 1/2" metal conduit (like this: https://www.homedepot.com/p/1-2-in-EMT-Conduit-101543/100400405).

I'm using this with a 21" and a 19" monitor. I have had it up for a few weeks with no issues. No guarantees on how strong it is for larger monitors, use at your own risk.
