My glorious full metal hotend is finally done.
It’s shiny and I only dropped it like once.
Brass nozzle with 0.3 mm diameter.
Heat Block for 5 mm heater.
Stainless steel heat break.
Aluminium cooler with M12 thread
and a PTFE guide tube that is screwed into the cooler.
All connections that have to take some force are metal to metal so in normal use this should be basically indestructible.
