a swivel-arm, but the weight of two monitors would be a lot for something like that
I’m still wanting to build a rolling desk myself and have some components already, but you might want this: Humanscale M10. It’s pricey but it’s the heaviest-load arm on the consumer market. It can take 48lb, and if that’s overkill, they have cheaper arms that will carry less. You might find some of the cheaper brands will do what you need without the cost, but I don’t have experience with them.
Skip their expensive crossbar adapter though, you can use any much cheaper VESA bracket adapter, you just need the arm itself to be solidly constructed.
The real issue for the design you have in mind though is center of gravity. You’re stuck with attaching it to something very heavy and wide. I’m still in the early stages of fixing that problem myself. My solution is likely to involve significant amounts of V slot aluminum profile.


There are, and the rules for each community (subreddit) differ, but there are also the instance (server) rules, so it can get a bit complex. The community rules are usually posted in the “sidebar” for that community, eg. https://lemmy.world/c/asklemmy, the instance rules you’ll usually find in the “sidebar” for the servers home page, eg. https://lemmy.world/. you can tell what instance a community is in by the community name, if it doesn’t have a “@” in it, it’s on the same instance you are.
Just have a quick look at both sets of rules before you post something and you’re probably fine. Even if you get banned from one community or instance, there are likely similar communities and instances elsewhere you can go. The biggest difference will usually be how active they are. You can also set up your own community, and if you’re tech oriented, your own instance.
