Raise3D N2 Heater Block Wrench (Long)

This is a long version of the excellent hot end wrench: http://www.thingiverse.com/thing:2049806

I extended the arms to allow using the tool from the back, as I have a fan blocking the front of my hot ends. When combined with my heat shield, it allows me to change nozzles without disassembling anything.

Print with polycarbonate or other high temperature material. I heat my hotends up to 140 when removing the nozzles. This prevents the tool from melting or deforming.
