Control Arm Knob for Original Bladerunner

thingiverse

The original bladerunner control arm knob was way too small for me with big hands and now arthritis settling in, it was impossible to tighten down the arm enough to hold material in place. I made this so that the handle fits snugly on the nut instead of the nut fitting in the top of the knob as it does in the original version. Now I can get a grip on the thing and easily secure the arm position with no worries.
