Replacement knobs for the Korg Monologue (may also work for the Minilogue - someone please verify if so). These are about the same size / shape as the OEM knobs, but with a knurled finish in place of the factory rubberized coating (which tends to deteriorate and get sticky / nasty after a few years). The pot / encoder knobs were generated with the excellent knob SCAD here. I built the slider knob in Tinkercad, which you can tweak here.

You'll need

• 15x standard knobs (with the indicator)
• 1x program knobs (somewhat longer stem and no indicator)
• 1x slider knobs

Tips:

• Print them upside down, with the knob tops on the build plate, to get a nice finish on the top, and avoid using supports for the twist knobs.
• The slider knob I also printed upside-down, with tree supports for just the little overhang bit.
• The silver bands in the photos were done with a layer change, swapping in silver PLA for the black.
