Third hand solder SMD

This small assembly makes it possible to maintain a SMD component plated on the printed circuit while it is soldered.

To realize this assembly, it is necessary, in addition to two parts printed in 3D:

* A small spring: I got it on an old clothespin
* A needle: type “needle smd” into a search engine.
* M4 screw / nut

It’s a simple montage, inspired by this one: SMD solder holder I found the idea very good, but I wanted to improve 2 points:

* An impression without support
* Simplify editing by removing the gallows.
* And by the way, also to use a model of spring and needle that I recovered
