Extra Large Star Knobs – Two-Part Design (M4 to M12)
Enhance your tool and equipment builds with this two-part, extra large star knob set, designed for hex-head bolts from M4 to M12. Engineered for strength, ease of assembly, and excellent torque control, these knobs are ideal for a wide range of workshop and maker applications.
Key Features:
✅ Two-Part Design
Each knob is split into a top grip section and a bottom hex socket base, allowing for easier printing, cleaner geometry, and strong mechanical performance

🔩 Hex Bolt Ready (M4–M12)
Designed to securely accept standard hex-head bolts (not socket caps), with precise cavities matching M4, M6, M8, M10, and M12 heads. Eliminates the need for threading or inserts
🧲 Friction-Fit Assembly
The two parts snap together with a tight friction fit, ensuring a strong hold without adhesives—yet still serviceable if needed
✋ Extra Large Star Grip
Oversized star-shaped handle offers improved torque and ergonomic comfort for manual fastening, even with gloved hands
Advantages Over Traditional One-Piece Knobs:
- Better print orientation (no support under overhangs)
- Cleaner internal geometry for bolt fit
- Stronger mechanical engagement
Included:
- 5 size variants: M4, M6, M8, M10, M12
- STL files for both knob halves per size
Suggested Uses:
- Jigs, fixtures, and clamps
