Here is such a simple, and most importantly, a device necessary for work that everyone can do at home with their own hands. It will take no more than 15 minutes, but working with a soldering iron will bring benefits and convenience.
What do we need ?! Ballpoint pen and thin solder straw.
Agree: it is not always convenient to unwind solder every time or hold the coil in your hands when soldering. To do this, we will do this: take the paste from the handle and wind the solder on it as in the photo:
Immediately for the future we will produce several wound blanks.
Insert into the case from the ballpoint pen and get a convenient fixture for soldering.
Very convenient: we hold a soldering iron in one hand in the other fixture with solder.
