Do you have a link to one of these third-party ones that could act as a substitute? I couldn’t find one that is short enough (the closest I could find is a 2" one, which is still too high) Other than using them flat, I’d probably just stuff enough paper or cloth scraps until the entire hollow space below the keyboard was filled up if I really wanted to keep tenting them, but I’ll probably just end up using them flat if it’s so troublesome.
