However the are dozens of different categories/profiles most probably due to heat resistance etc. If in doubt I'll ask Makergear support - just want to avoid that the insulation later on melts on my hotend :...

Now I'm investigating what's wrong and it seems that the v3b uses a groove mount which is not properly sitting anymor...
