Fluke 87V Knob (dial)

The knob of the famous Fluke87V is breaking easily on the bolt diameter reduction for the sealing O-ring. I designed a new Knob with separate hexagonal bolt in order to print the bolt laying on bed so getting more resilience to torsion. So after that I designed a knob with a hexagonal slot where the bolt can be glued. I took out the sealing O-ring to keep the bolt section on all the length. I use supports enhancer in Prusa slicer only on the indicator of the Knob
