Breadboard Jumper Tool, 3D Printed Workshop Tool

Design preview. Rendered from the file, not a photo.
This model is not currently offered as a verified ready to buy print.
What it does
- Cut wires to exact lengths so your breadboard jumpers fit perfectly every time
- Mark strip points accurately so you remove insulation from the right spots
- Make jumpers in minutes instead of hours, so you build circuits faster
- Works with standard 22AWG wire and fits any breadboard layout
You spend less time measuring and more time building when you use this breadboard jumper tool. Stop guessing at wire lengths and stripping the wrong spots. This 3D-printed template handles the math for you.
Here's how it works: pick your jumper length from the right column and cut your 22AWG wire. Find the same number on the left side, center it on the template, and mark both ends. Those marks guide your wire stripper to remove coating in the exact right places. Then bend your wires and you're done.
Compatible with Arduino breadboards and any standard protoboard setup. This tool saves you mistakes and frustration on every single jumper you make.

What it is made of
Designs like this print well in PLA. Compare the materials.
Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
