Adjustable Component & Wire Bending Tool

Always the right length!

Compared to a common bending tool this adjustable one can be set to the wanted length. It can form long wires for breadboard use as well. Even diagonal connections with unique lengths are no problem.

A paper about the tool was published in the special issue 7/22 „Elektro Technik“ of the German MAKE Magazine. 

UPDATE 18.01.2023: I added the files for a version with 2mm wires as pins. For this version is also a blender file available. Thanks @Carsten (https://www.printables.com/de/social/15695-carsten) for that cool modified version!
