📖 Description
Bring that classic, oversized boutique look to your gear! This 25mm diameter knob is inspired by the iconic MXR and Fender styles, offering a professional aesthetic and superior grip for your pedals, amps, or synthesizers.
Whether you are building a "vintage-correct" clone or just want a more tactile feel for your favorite stompbox, this design is the perfect balance of form and function.
🛠️ Technical Specifications
- Diameter: 25mm (Oversized for better grip/look).
- Compatibility: Designed for 6.35mm (1/4") potentiometer shafts.
- Fastening System: Set-Screw design for a rock-solid grip.
- Hardware Required: 1x Standard M3 Nut + 1x M3 Set Screw (Grub Screw).
🔧 Assembly Instructions
- Insert the Nut: Slide the M3 Nut into the internal hexagonal slot.
- Prepare the Screw: Thread the M3 Set Screw into the hole until it meets the nut.
- Mounting: Place the knob on your 6.35mm shaft and tighten the screw until it locks firmly.
🎨 Printing & Finishing Tips
- Resin (Best Result): Highly recommended for that smooth, injection-molded look.
- FDM (PLA/PETG): Use a 0.2mm nozzle and 0.1mm layer height.
- The "Pro" Look: Print in black and use white acrylic paint or a paint pen to fill the indicator line for high contrast.
- Color Choice: Don't feel limited to black! Print or paint in neon, transparent, or metallic filaments to make your gear stand out.
