I created a laptop and docking station 2 in 1 mount for my Secretlab Magnus Pro sit/stand desk. I already had my desktop hanging on one side of the desk and there was no solution available to hold a laptop/docking station underneath the desk.

The mount uses x2 - M3 screws and x2 - M3 nuts to hold it together and 1/8" foam for padding and friction to hold everything in place. The foam lines each part of the bracket so the laptop/dock do not rest on the bracket. The laptop I used to design the bracket is an HP860G8 and an HP G5 USB-C docking station. I uploaded the raw files for it to be resized to fit your need, but since it is a friction mount, you may be able to compensate with various thickness of foam. Since the 2 sides of the bracket are independent of one another, you can install just the laptop section without the dock portion of the bracket.
