2.54 mm / 0.1" Wire Bending Gauge

2.54 mm / 0.1" Wire Bending Gauge

A simple jig for bending electrical wires and component leads to repeatable dimensions for breadboards and PCBs using the standard 2.54 mm (0.1") pitch.

Instead of measuring and bending each wire individually, simply select the numbered position on the gauge and use the corresponding step as a bending reference. The design provides multiple repeatable bending positions in one compact tool.

Features

• 17 indexed bending positions

• Designed around the common 2.54 mm / 0.1" electronics pitch

• Useful for breadboard wiring and through-hole PCB work

• Helps produce consistent, repeatable wire bends

• Compact and easy to keep next to your soldering station

Typical uses

This gauge can be useful for:

• Preparing wires for breadboard circuits

• Forming jumper wires

• Bending component leads before soldering

• Preparing wires for through-hole PCBs

• Reproducing identical wire shapes when building multiple circuits

• Quickly creating clean and consistent right-angle bends

How to use

1. Select the numbered position corresponding to the desired bend dimension.

2. Place the wire into the appropriate section of the gauge.

3. Bend the wire against the gauge's edge/step.

The numbered positions provide a convenient reference so that the same wire geometry can be reproduced without repeatedly measuring with a ruler or caliper.

Printing

The model is designed with straightforward geometry and is suitable for typical FDM printing.
