Hello World!
To use my old monitor arm i needed to adapt the vesa100 pattern of my monito to vesa75. I Also needed to lift the assambly by 10mm to get out of the way of the monitor backplate.
I printed the model in PETG but PLA will do as well. I Used m4 threaded inserts for the vesa75 hole pattern and m4x10 screws to mount plate of the monitor stand. To fix it to the monitor is just used the included hardware (m4x15).
The author marked this model as their own original creation.
