Volume Knob for ICOM ID-5100 Radio

This is a replacement volume knob for the ICOM ID-5100 radio designed for improved grip and usability. 

The knob features a D-shaped shaft hole (4mm diameter with one flat side) and incorporates multiple textured surfaces for better tactile feedback and grip during operation. 

Important note: You must remove and reuse the D-shaped metal clip from inside the original knob before installing this replacement.

Key features:

• Optimized for 3D printing with 0.4mm nozzle
• Enhanced grip with textured lateral surface and grid pattern on top
• Three-tiered design with smooth base and textured upper sections
• Compatible with ICOM ID-5100 radio's D-shaped 4mm shaft
• Position indicator on the side for visual reference
• Shaft depth: 7mm
• Requires the D-shaped metal clip from the original knob

The knob's surface includes a specialized texture pattern designed to be easily printable while providing significant improvement in grip compared to smooth surfaces or traditional knurling patterns that may not print well at smaller scales.

Perfect for radio enthusiasts who want to replace their original knob with one that offers improved handling, especially in mobile or field operations where precise control is essential.
