Hi everyone, I'm sorry for my English but I'm Italian and I use Google translate 
I had many problems related to bltouch and the high temperature (> 80 °), in practice I noticed that the stick being made of plastic, it embarks.
If you've ever bought an inexpensive bl-touch, you may have noticed that the stick is made of aluminum, which doesn't mess with temperature.
The simple solution I found:
- take original bltouch stick (plastic), cut the magnet and keep it for later.
- take aluminum stick, remove magnet and hold stick.
- with pliers, squeeze the stick to create the thickness that stops the stick from falling (the precise height of the enlargement, see Original Stick).
-limate the face of the magnet to be attached and the face of the stock to be attached. - attaches original magnet with aluminum Stick, using Attack (they must be perfectly aligned).
- now put all this, in the original bl-touch.
PS. I shortened the aluminum stick to make it lighter, I don't know if it is essential.
