Universal 6 mm Encoder Knobs – Tapered Design for Easy Control 🎛️

I designed these knobs after getting a Rotel amp that was missing one — but since it uses standard rotary encoders, they’ll work for any encoder with a 6 mm shaft and central slit (a common split shaft style in audio gear, mixers, and electronics projects).

📏 Dimensions & Compatibility

• Inner Diameter: 6 mm — fits standard rotary encoders with a central slit (split shaft).
• Outer Diameter: 20 mm — comfortable grip without taking too much panel space.
• Works with most audio amplifiers, mixers, and other devices using similar encoders.

🎨 Design Features

• Round base with tapered top for smooth, comfortable turning.
• Minimalist shape blends with modern and vintage gear alike.
• Single-color design for quick and easy printing.
• Also available in a multicolor version for an enhanced look — Multicolor version.

🖨️ Recommended Printing Settings

• Layer Height: 0.12 mm for a clean, detailed finish.
• Walls: 3 perimeters for strength and durability.

Perfect for: Rotel amplifiers, audio projects, synthesizers, mixers, or any gear using a 6 mm split shaft rotary encoder.
