Posted this to reddit some time back, reposting here because I want to contribute some content and help lemmy gain popularity.
I hope that in a few weeks I will be posting an updated version of the setup with the laptop replaced by a third monitor and a few other modifications.
I bought it under a “HAKNER” brand but I’m afraid this won’t really help you because they just seem to be a Polish importer. When I posted this to reddit, someone actually found this: Jarvis Single Monitor Arm. I can’t vouch for this because it’s not where I bought it, but from the photos it looks identically, to the smallest detail.
