Another solder spool holder, this one has a threaded spool rod. I had an old soldering iron stand which I mounted the solder spool holder on, the sponge area makes for a nice drip plate for the solder :) .

Because of the threading, use the best resolution you can, you can clean up the male threads with a small file. If need be, GENTLY heat/warm the threaded portions the first time you screw them together.
