Nut for KSGER soldering iron with T12 tips (perhaps suitable for other T12 soldering irons). The nut allows you to quickly replace the tips without the need to tighten them with nuts. The nut has a latch that holds the tip in place.
Due to the necessary flexibility and temperature resistance of this element, I recommend using PA12CF.
ABS, PETG, PLA are not suitable for this purpose.
It is necessary to use supports for proper printing.
