Laptop Adapter Bracket for Dual Monitor Stand

thingiverse

I wanted a way to mount my laptop on my existing monitor stand so that the screens would be at the same working height. This required lowering one of the arms, but they were attached by a shared bracket. This was my solution. I don't know the brand of the stand I have and I can't guarantee this will fit any particular stand, but maybe it will be a good starting point for you.
