What it does
- Bend resistor and diode leads uniformly every time, no more wonky wires

- Compact tool that earns its spot on your workbench
If you've ever squinted at a breadboard full of resistors bent at slightly different angles, this 3D printed workshop tool is about to become your new best friend. The Resistor Lead Forming Tool does one thing beautifully: it bends resistor and diode leads to the exact same spacing, every single time.
No more eyeballing. No more re-bending. Just slide your component through the guides, make your bends, and you're done. It's oddly satisfying, and if you've got little helpers at home who are curious about what you're building, this is a perfect (and safe) way to let them pitch in.
Whether you're assembling a through-hole project or just prepping a pile of components for later, this little jig keeps your work neat and your sanity intact. It's the kind of simple, clever tool that makes you wonder how you ever lived without it.
