Adapter to mount a VESA 75 object at a 45-degree angle. I wanted to mount a laptop tray to a monitor arm. Angle did not work out, so I made this adapter to be able to mount the notebook tray at a 45-degree angle. This adapter fits VESA 75 on both sides. One side takes an M5 bolt, the other one an M4 bolt.
Holds my Dell Precision 5750 ('thin and heavy') without problems.

Using this on a Humanscale M2 arm with a PureMounts PM-ADAPT-NBW tray.
