I've been trying to find vendors who sell the parts to build stands like that. Ideally I'd like the column height to be adjustable, but I obviously can't come up with the right words for a search because I can't find them even in fixed height.
I'd like to build one specifically for a DEC GT40 terminal, with a keyboard tray. Someone I know has a stand that is almost perfect for the GT40, but there's no identifying information on it, so I can't easily search for a matching stand.
