This is a form to bend a 2.5-3mm wire into a coil as a stand for a ts100 or similar soldering iron. I used a cloths hanger, but sanded the paint off first so the hot iron wouldn't burn it.

After forming the end can be cut with a hacksaw to make unscrewing it easier. The offset top makes it harder to unscrew without deforming. You could try cutting it apart before unscrewing. I may post a two piece design if there are any requests.
