RepRap Prusa Mendel Hot End Thermistor Wire Tie

While I was building my RepRap, I had the thermistor pull out of the Kapton tape on my hot end. My kit from MakerGear included some 4-stranded wire with a steel wire and nylon string inside it. I took some of the steel wire and wrapped it around the hot end, snugging the thermistor in place.

That thermistor isn't going anywhere.
