Small soldering sponge holder

I made this sponge holder to keep it in my soldering toolbox without having tin/lead fragments running everywhere from the sponge.

The cap is screwed (more like a quick connect) and depending on the tolerances of your printer maybe too tight or too loose.

If you feel it is way too tight, try shaving a little bit the cap brackets as shown in the picture. An exacto knife works well or a cutter, but be careful and shave a very little amount at a time to keep a bit of friction.
