If you have a 3D printer, you can download a file on thingevers for the adapter. I have drawn it myself. In an emergency I could also print it for you.

Thanks Jan for your tip👍😉

You'll have to build it yourself. I've bought the Montior twice, once as a second-hand item, and the previous owner threw it away. I couldn't order the part anywhere, not even from Samsung directly. But it's actually quite easy to make it yourself.
