Finecoar Dial – No M5x30mm Threaded Nut Needed

Version V2:

This version builds on an alternative model that avoids the need for the M5x30mm threaded nut required by the original Finecoar mod. To visually match the Finecoar setup, I added the original lettering from the Maker World version. I also adjusted the mounting hole to fit a M3x8mm screw flush with the surface. Using a longer screw will cause it to protrude, so a M3x8mm screw is recommended.

Version V1:

This earlier version fits directly over the original Eureka knob and replicates the Finecoar knob's basic functionality. It also eliminates the need for a M5x30mm threaded nut—only a short M3 screw is required to hold it in place. I used a M3x8mm screw, which protrudes slightly but doesn’t affect function. However, this version lacks the visual refinements of the full Finecoar setup and doesn’t fully match its design aesthetic. That’s why I designed Version V2.
