Fisher 400-C Switch Knob

thingiverse

This replacement knob is designed for one of the switch levers on a late 1950s Fisher preamp. Other models may also utilize this knob. When printing this design, ensure the dished side faces upwards. Unfortunately, I didn't have any PETG in brown available. After applying primer to the finished knob, I sprayed it with a coat of brown paint to match the original color. The resulting knob isn't flawless but is still quite satisfactory and significantly better than not having one at all.
