Their knob is the Mazzer OEM part and that little piece of metal is included. With a few simple tools and bit of ingenuity you could probably make that part yourself. I'll try tonight to pull that piece from one of my spare knobs and post a few close-up photos and measurements. Have you tried turning the shaft without the knob in place and confirmed that the timer switch is okay.
