This is the stand for TTC Vision3 HMI unit: https://www.ttcontrol.com/products/visualization-hmi/rugged-operator-interfaces/vision-3/
I found it handy during Front Panel app development to have the screen attached to the stand. It is possible to position the screen horizontally and vertically.

Hardware needed:
Knob - mount plate connection: M4 23mm or longer + nut
Arm - base plate connection: 4x M4 12mm + nut
Vision3 + mount plate connection: 4x M4 8mm - 10 mm

I uploaded also a source drawing made in Designspark Mechanical if anyone will need to edit it.
