Universal  auto-adjustable  D-shaft knob cap with numbered dial plate set, ideal for rotary switches, rotary encoders and potentiometers.

Perfect for use DIY electronic projects, guitars, amplifiers, MIDI controllers, vintage-style equipment, and so on.

This design offers a clean appearance, excellent tactile feedback, and highly visible numbers for precise adjustments.

For best visual results, I recommend printing the numbered dial plate using a 3D resin Printer. The numbers are embossed, allowing you to easily highlight them by applying paint over the surface without affecting the plate itself. A white permanent marker also works very well to improve contrast and visibility.

The inner profile is designed to provide a secure friction fit on standard potentiometer shafts, helping prevent the knob from slipping or falling off.
