Avid Mojo knob

Avid Mojos are getting old and the control knobs are notorious for crumbling inside.

I designed this replacement knob and it fits perfectly. I printed mine from translucent blue PETG but I'm sure any filament would work. I printed this knob 100% infill (lines) PETG nozzle temp 250C bed 80C 50mm/sec on carbon fiber bed. No support. Orient the knob face down so the insides are printed from the flat of the knob up to the open portion of the part.
