🔧 Customizable Fuel Pump Lock Ring Removal Tool (Wrench Head)

This is a fully parametric design of a precision-fit wrench head to remove and install slotted fuel pump lock rings. Say goodbye to hammer and chisel.

By controlling every dimension, you can easily adapt this tool to match the lock ring assembly of almost any vehicle that requires a specialized slotted wrench.

🖨️ 3D Printing Recommendations

To achieve a tool robust enough for high-torque applications, the following settings are crucial:

1. Material: Recommended PETG (good mechanical resistance) or even ABS/ASA
2. Infill: 100% for maximum strength. This tool must withstand significant pressure (i've tried with 30% Gyroid and it was fine).
3. Perimeters: A minimum of 5-7 perimeters (wall lines) to increase structural integrity and circumferential strength.
4. Layer Height: 0.2 mm (Standard) or lower for better precision in the slot features.
