Six-Lobe Replacement Knob | Parametric CAD Concept

Report
# Six-Lobe Replacement Knob A self-initiated parametric CAD study of a small replacement component. Six scallops provide finger access around the knob. The underside contains a recessed D-shaped shaft socket, while a separate cap provides space for a position indicator. The second view reveals the shaft interface. ## Design details - Maximum diameter: 46 mm - Total height: 21.5 mm - Nominal D-shaped socket: 6.3 mm - Modeled in CadQuery and rendered in Blender These dimensions are concept inputs. Adapting the design to an existing appliance or machine requires measuring its shaft and testing the fit.
