Solder Scroll cho người thuận tay phải

I like the original design, but it seams it is designed for left handed. My right hand is reserved for the soldering iron. So, the files are mirrored, to be used with left hand.

It sits better in left hand, and scroll cog does not poke the finger. The cover part is also bit modified for better grip, and it covers the small cog. I would advise to use this modified spool instead of original: https://www.printables.com/model/846835-modified-spool-for-solder-scroll/files

Other files (clips) are unchanged, and should be used from the original design. 

As the files are mirrored, the nut is counter thread, so tightening is cone by turning it to the left hand.
