Summary

I have a few Lutron timer switches in my home, type MA-T51. The "knob-plate" of one of them was lose, a few parts broke off. This replacement knob should be printed with supports. Be careful when removing the supports, the knob is fragile. Same goes for inserting the knob into the Lutron timer, try to keep it straight, do not use force. Once the knob is in place, it will function forever.
