This was my first attempt trying to use stick welder to make an iron box, in fact this object I made is not even close to a box. Then I learned how to adjust the current to the right amount to weld a thin sheet of iron.
In my second trial to make a box, I was able to make straight welds on each edge even though I needed to practice more.
This is a 3D printer filament spool holder that can be mounted on the wall. I made this from scrap iron pieces and it has much stronger welds than the previous trials.
This is an adjustable printer stabilization part that that makes the printer much more stable and increases the layer quality to a great extend. Again I made it by precisely cutting and welding scrap iron pieces.
