This is my version of the Standsome height adjustment standing desk.

I modelled in Fusion 360 and then cut on a laser machine with 13mm plywood. Unfortunately, the laser cutter in https://motionlab.berlin was not able to cut through it and I had to finish by hand. The vertical part is smaller than in my design because I was using scrap materials ;)

If you want to make it with a cnc machine, you should modify the design because some of the corners are 90º.
