I modified the soldering iron holder from https://www.printables.com/de/@John_248786 and clamp to fit the dimensions of my soldering iron.

The clamp and holder are attached with 4x M3x16 mm screws, and you should also insert 4x M3 threaded inserts into the holder.
I printed the mounting in rPET from Formfutura. To see if it could withstand the temperatures, I set my soldering iron to 450°C and left it on for 10 minutes.
It worked completely fine.
The author remixed this model.
