Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

This EC12 rotary encoder knob by Oak Ninja, covering the encoder base, is perfect for low-profile encoders with D-shaft. It fits encoders like EC12E1220301 and EC12E2440.

It was really hard to find a nice EC12 encoder knob so I decided to design my own, and I’ve finally settled with a design that I’m happy with – OakNinja.

The knob is compatible with MX-spaced Choc switches but the author thinks it may work fine with Choc spaced switches as well.
