This is my Solder Sustainer v2 project! The predecessor of my first version that I built and designed back in July 2023.

With this, you can solder with precision while only utilizing one hand, freeing up your other to hold whatever wire or component you are trying to solder. Being that the solder guide is around your finger, it allows you to direct the solder more accurately so that you can solder things with the same precision that you normally would with two hands. You also don’t need to press a button on the iron to extrude anymore (like the v1), since the extrusion and retraction tasks are being handled by two wireless foot pedals.

If you want to learn more, everything else about the project can be found here for free: https://www.roboticworx.io/p/build-a-one-handed-soldering-tool-bc7 (just click "dismiss" at the bottom if you get a pop-up).

NOTE: The Gerber attached is for right-handed users only! The left-handed Gerber can be found here on my GitHub page.
