My daughter got her braces off yesterday. Hooray!
She has a bunch of leftover rubber bands, and I want a damper to keep Model M/Fs (catch the clever pun?) from bottoming out.
I have tried one and it seems to work, but it stretches to a very thin cross-section by the time I work it all the way in.
I would prefer a real O-ring, but the ones for plumbing are far too fat and prevent the key from working properly.
McMaster-Carr is local for me, but they won't let me see the merchandise before I order it.
Has anyone found the right fit for the IBM key stems?
thanks !
