Headset side mount hanger

I liked the idea of the original model, but I felt like the screw needed better contact to stay flush with my desk. I added a “nub” to the end of it which allows a flat plate to attach to it. I used the idea of the nub and plate from another model that I used for a cup holder. Neither of these were my idea, I simply put pieces of them together to make them work for me. I'm only adding the stl I created for the modified screw/knob. If you need the other parts, including the plate that goes on this, please see (https://www.printables.com/model/88860-cup-holder-clamp-3-no-supports)
