Mendel90 Hot End
I've just finished making a new hot end for a new extruder: It is based on one of
designs and has a few interesting features:
There is a grub screw to prevent the brass nozzle from working loose.
The brass nozzle is screwed into both the peek and an 8mm internal PTFE liner. The nozzle thread has been coated with high temperature silicone to improve the seal.
At the other end there is a 4mm high, M9 threaded brass plate with a slot to push down on the PTFE liner to prevent it moving.
Haven't had chance to try it yet.
