So I was walking around IKEA with my special someone, looking at stuff to buy for our new appartment. Then I saw this laptop-stand, and I got an idea. I have been looking for a joystick-stand for my TMWH stick that is hight-adjustable.
I turned it over, and found that the tabletop is held to the stand via a round, plastic platform, about the size of the TMWH stick base. Some new drilled holes and it should fit nicely. And it was only $15.
So I bought it, and drilled the new holes. It works like a charm!
This is the table, as intended. Called Svartåsen at IKEA.
And this is the result. It is actually really solid, no jiggle at all.
