RepRapPro announced their new hot end a few days ago, replacing the brass nozzle with a one-piece stainless steel part. There is still a PTFE piece inside to accommodate 1.75mm filament, but I have been wondering whether it would be possible to modify this hot end for 3mm? As far as I can see, the OD of the PTFE liner is 3mm, leaving a little bit of room to the walls of the barrel.
So has anyone tried just removing the liner and using the hot end (or one of the predecessors) as an all-metal one? Also, do you happen to know where I can find the drawings of the parts? I have checked their github repo, and the wiki, but could not find anything - and I cannot imagine it being closed source.
