Control Arm Knob for Original Bladerunner

thingiverse

The original Bladerunner control arm knob was far too tiny for my large hands, making it impossible to tighten down the arm securely with arthritis now settling in. I designed this to fit snugly around the nut instead of having the nut sit on top of the knob like the original, allowing me to grip the handle firmly and easily secure the arm position without a single worry.
