This is just the hotend, but I recycled most of the parts from my MP3DP V2 H2 hotend. I also created the Part Cooling fan duct to more properly fit the origial and V2 versions of the H2 Hotend. Shown is the 4020R version, but I also have a 5015R and 5020C versions as well (but not real world tested yet.
See attached pics and assembly diagram.
