Tip maker for soldering pistol

I made a tip maker for my soldering pistol. this pistol is specific in my country as a DIY pistol made by people who are better at electrical devices and so on. This pistol is made to resist more lifecycles than a market one, and the particularity to this pistol is that you have to buy a cooper wire and make yourself the tip. depending on the diameter of the copper wire and the length of the tip, the tip could last more or less. Mine is lasting up to 5 solderings ( I don't know why ) and I needed a way to make those a bit quicker.

this is the first project and It does need to be adjusted to a more efficient way, I made it in a rush because I really need it, in the future, I will try to upgrade it or develop it in a better way, right now, after you make the tip is a bit difficult to take it out without bend it back a bit.
