Did this have the desired effect of making the keys less stiff to press?

Hi Jeff, I think so yes, but I think I also need to add a caveat which I didn't see mentioned before, and that is, we need to be mindful just how much we "flex" these keys. After I just pressed them a bit, flush to the keypad surface, I found that some keys were still stiff. So I pressed all of them again, a bit more, and I discovered some were TOO easy to press (just a bit too easy). Actually maybe that's not really the problem. The problem is the differing resistance, since the keys are now sort of non-standardized, with very unscientific flexing across the board (literally).

That's all I would add about it but I think definitely I would flex them again if I purchased another DM42.

(If one is so inclined, I think one could 3D print a bottom "tool" layer to put the keyboard on, with bumps that are "calibrated" to allow only a certain travel distance for the flexing, to make it a bit more of a scientific home-brew solution.)
