Universal D-Shaft Control Knob (6mm)

Replacement control knob designed for devices that use a D-shaped shaft. The large profile provides a comfortable grip, while the built-in indicator makes it easy to see the knob position at a glance.

A viewing opening at the top allows you to confirm that the shaft is fully seated during installation, helping ensure a proper fit.

Designed for a 6mm D-shaft by default, but the model can be scaled up or down to fit other D-shaft sizes. Small scaling adjustments can also be used to fine-tune the fit based on your printer's tolerances or how tightly you want the knob to fit on the shaft.

Compatible with a wide range of equipment that uses D-shaped shafts, including fire pits, grills, appliances, electronics, tools, and more.
