15mm Knob for 6mm D-shaft with Indicator

thingiverse

I crafted a knob for my Yamaha SU700 sampler, which was woefully bereft of its knobs when I acquired it. To ensure a snug fit, I printed the design upside down, anticipating that slight adjustments might be necessary depending on one's printer tolerances. Rather than setting up a dual extrusion print, I opted to paint the stripes onto the knob itself.
