Volume / Potensiometer Knobs Collection

🏷️ The Ultimate Retro & Hi-Fi Knob Collection

Precision Engineered for 6mm Shafts | Parametric-Ready

Give your DIY projects a professional, factory-finished look. Whether you're upgrading a 90s-era PC case, finishing a pair of custom bookshelf speakers, or restoring vintage audio gear, this collection is designed to provide a perfect fit and a premium tactile feel.

✨ Style & Utility Pack

I have organized this model into three distinct styles and three industry-standard sizes. No more "guessing" if a knob will fit—this pack covers the most common electronics hardware found today.

Size	Outer Diameter	Height	Recommended Use
Compact	15mm	15mm	Guitar pedals, flight sims, and dense control panels.
Classic	20mm	17mm	Standard Volume for desktop speakers and PC mods.
Hifi	30mm	18mm	Main Master Volume for Hi-Fi receivers and amps.

🛠️ Technical Design Features

Universal 6mm Fit: Optimized for the most common potentiometer shafts (Round, D-Shaft, and Knurled).
Nut-Hiding Recess: Each knob features a 12mm x 2mm internal recess on the bottom. This allows the knob to "swallow" the mounting hardware, sitting flush against your panel for a professional look.
Retro Aesthetics: Ribbed side-walls and precise fillets inspired by 90s industrial design and high-end laboratory equipment.
Support-Free: Designed with 45-degree internal chamfers to ensure a perfect print with zero supports.

Layer Height: 0.12mm (Highly recommended for the side ribbing detail).
Walls: 3+ Walls for a solid grip on the shaft.
