The mount is a good idea, no question, but it has several disadvantages. 1. the holes are not aligned so that the screws have to be inserted at an angle on one side 2. stability is rather mediocre 3. the cut-out for the Cloudkey is 1-2mm too narrow 4. the dovetail needs too much force and can break away In the end, I designed the whole thing myself based on the idea here.
