Fits the solder tube that comes with this soldering kit, and should fit other similar solder tubes with a bottom diameter of around 15.40 mm and a top diameter of 16.85 mm directly below the cap.

Since the solder tube is an upside-down frustum, I have made the hole wider at the top than at the bottom.
