G90 Tuning Knob

thingiverse

I designed a larger tuning knob for my Xiegu G90, as the stock one was too small to turn smoothly. To improve usability, I created a simple design that fits atop the original knob. The new knob is significantly easier on the fingers and allows for faster scrolling through the dial. To ensure smooth edges, I printed it at 0.1mm resolution. I used supports during printing due to issues with my printer's ability to print over empty space. However, your results may vary depending on your specific printer model. The knob fits perfectly on my radio without any modifications required. You might need to sand the inside or apply a thin layer of tape for a snug fit, but scaling up or down can also work.
