Flashforge all-metal hotend

This isn't a printable item, but I figured I'd post it here anyway since it's somewhat relevant and I've got a 3D drawing of the piece to show. Might come in handy if you have the requisite tooling to make this part. I came up with this design by putting together some elements of E3Dv6's heat break (ultra-thin heat transition zone with 0.4mm walls) and Jetguy's brass nut trick, which helps conduct heat from just above the transition zone to the aluminium cooling bar.
