Just curious, has anyone ever tried 3D printing replacement knobs? My Tek equipment is all intact but I could use a few HP knobs as well as a couple of Genrad. That might be a nice little sideline for someone to help justify the cost of a good quality printer. Getting the color bang on would be an issue and a 4th axis to rotate the knob as it's being made might be necessary for really good authenticity. Still, worth exploring?
