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.

I had some issues with the wing nut/bolt holder pieces slipping when the bolt tightens, that's why I included a couple of different designs. The wingnut/bolt holder pieces are optional, you could use just bolts and tighten with a wrench.

I have included a plain mount and a 2nd with 5-degree angle. Even greater angle would probably be better for my setup, maybe 15 degrees.

The base uses 4 bolts (length depends on thickness of mounting surface) and 4 nuts. Per monitor, you'll need 8 bolts and 4 nuts. (All M4 metric bolts & nuts.)
