Don't do it - Hot end

This is a dangerous thing the following reasons:

- Nichrome around steel: many chances for a short sooner or later thus many chances for, at least, extruder controller death.

- It constantly leaks some baked-rebaked-ultrabaked abs (volume like a drop of water every... +/-10cc of extruded ABS), the fumes are everything BUT healthy.

The electrical failure plus catastrophe side is reinforced by a low mass design and thermistor most probably not placed in
