Lever-Action Mini Fuse Puller (No Supports)

Heavy Duty Mini Fuse Puller (Clothespin Style)

Tired of flimsy, fragile OEM fuse pullers that bend, twist, and slip off stubborn car fuses? This is a complete redesign of the classic workshop tool, engineered specifically for 3D printing and extreme reliability.

Instead of a basic, weak tweezer design, this model utilizes a clothespin-inspired lever mechanism.

How it works:

The tool features integrated internal pivot points (stoppers) located just 7mm from the tip. When you squeeze the grooved handles, these points lock against each other, transforming the tool into a dual-sided lever (like scissors). The harder you squeeze, the tighter the 1.8mm jaws clamp onto the fuse. No bending, no twisting, no slipping!

Key Features:

• Ultra-Rigid Geometry: Shortened to 55mm to minimize flexing and maximize leverage.
• Smart Lever Mechanism: Internal stoppers prevent the arms from twisting and multiply your grip force.
• Print-in-Place: No assembly required, print and use immediately.
• 100% Support-Free: Designed with clean angles for a fast and flawless print.
• Ergonomic Grip: Grooved sides for a secure hold even with greasy fingers.

Recommended Print Settings:

• Orientation: Print flat on the bed (as oriented in the STL).
• Wall Loops: 4 - 5 (CRITICAL for structural strength—this ensures the spring ring and arms are printed as solid, continuous filament lines).
• Infill: 15-20% (with 5 walls, the narrow parts will be 100% solid anyway).
• Material: PLA (works great due to its stiffness) or PETG/ABS for higher glove-box temperature resistance.

[PL] Heavy Duty Car Fuse Puller / Grabber

Tired of flimsy, factory tweezers that bend and slip off stubborn fuses? Here is an improved "Heavy Duty" version, designed from scratch with 3D printing in mind.

Instead of classic tweezers, the tool uses a lever mechanism inspired by a clothespin.

How it works:

Inside the arms (7 mm from the end) are integrated stoppers. When squeezing the handles, the stoppers brace against each other, creating a pivot axis for the lever. Thanks to this, further pressure does not cause the plastic to bend into an arch, but rather multiplies the clamping force on the fuse itself.

Advantages:

• High rigidity: Length reduced to 55 mm eliminates the 'splaying' effect of the arms.
• Reinforced tip: The 1.8 mm narrow point easily fits into tight boxes, ensuring a solid perimeter.
• Support-free printing: Design optimized not to waste material.
• Secure grip: Grooved handles make work easier in the workshop.

Print settings:

• Number of perimeters (Wall Loops): 4 or 5 (CRITICAL – thanks to this, the spring-ring and arms will be solid plastic and will not break when tugged).
• Supports: None.
