Fluke 87V Knob (dial)

thingiverse

I redesigned the Fluke87V's knob because it was breaking too easily when the bolt diameter was reduced for the sealing O-ring. To make it more durable, I created a new knob with a separate hexagonal bolt that can be printed lying flat on the bed, giving it added resilience to torsion. Next, I designed a knob with a hexagonal slot where the bolt can be securely glued in place. By removing the sealing O-ring, I was able to maintain the bolt's section along its entire length. To ensure the design held up well, I used supports enhancer in Prusa slicer only on the indicator of the knob.
