Fader knob
thingiverse
Had broken a couple of faders on my Phonic Summit mixer so I modeled this from the existing faders. I'm pretty sure this will fit other mixers as well with minor adjustments. The center groove is meant to be painted white in oreder to easily align the fader to the underlying scale.
