Wire soldering pliers

English translated quote from original thing:
"
I needed a clamp to hold electrical wires together for soldering without them moving (they get hot between your fingers!).
You can find them on marketplaces, but when you need one quickly, you can make one yourself.

Plus, this clamp could also be used for connecting filaments, why not? Worth a try.

You'll need to find two compression springs, like the springs in a ballpoint pen.

I printed mine with 20% infill and a 0.6mm grid in normal mode.

I think this is a great tool, so I just want to be sure nobody ignores it just because they can't read french :)
