diy soldering iron

I wanted a portable soldering iron and I found out 510 soldering iron tips so I decided to use an old vape mod (voopoo drag) to make one.

parts list:
2m heat set inserts
2m screws

18650 batteries
gold plated battery contacts -https://a.co/d/66lJvd9

so far works great and heats up in seconds! also once the button is released the iron starts cooling so less likey to burn yourself.
