📖 Description

The iconic "Chicken Head" knob, reimagined for modern rigs!

Tired of oversized knobs cramping your style or blocking adjacent controls? This is your solution: a 25mm compact version of the legendary "Chicken Head" knob, a staple on countless amplifiers and effects.

Inspired by the sleek look of the EVH 5150 III amplifiers, this design offers that distinctive vintage vibe with a more practical footprint. It's perfect for:

  • Modern Amps & Pedals: Ideal for tighter control layouts where standard 32mm Chicken Heads are too large.
  • Synthesizers & Eurorack: Precise visual feedback and comfortable grip for delicate adjustments.
  • Custom Builds: Add a touch of classic rock style to your projects without sacrificing space.

Why you'll love printing and using these:

  • Clear Indication: The prominent pointer ensures you always know your exact setting at a glance.
  • Superior Grip: The ergonomic "beak" design provides excellent tactile control for quick adjustments.
  • Durable & Reliable: Engineered for longevity, designed to withstand countless tweaks.

🛠 Technical Specifications

  • Diameter: 25mm (Compact for space-saving applications).
  • Compatibility: Designed for standard 6.35mm (1/4") smooth potentiometer shafts.
  • Fastening System: Secure Set-Screw design for a firm, slip-free attachment.
  • Hardware Required: 1x Standard M3 Nut + 1x M3 Set Screw (Grub Screw) (4mm or 6mm length).

🔧 Assembly Instructions

  1. Insert the Nut: Slide the M3 Nut into the internal hexagonal slot.
  2. Prepare the Screw: Thread the M3 Set Screw into the hole until it meets the nut.
  3. 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.
