RigidBot Original LCD Buttons

Replacement buttons for the original RigidBot LCD display supplied with soft rubber keys.

I could no longer put up with the soft, constantly sticking LCD panel keys on our original RigidBot. If you have the same problem, here are some replacement keys I designed. Replacing the keys requires removing the LCD panel and then removing the four screws that hold the LCD electronics into the cover. Lift out the LCD circuit board and exchange the keys. (You need one BigBut and four LitBut keys.)
