I've thought about it, but if I were going to do a HoW exotics, I'd do the Lord of Wolves. The problem with that is that it takes so much material to actually print the thing, and it'd take forever to print. I'm just about to finish printing a Bad Juju and I've gone through 2.5 rolls of filament (2.2kg each roll)

Also, some sections on the bad juju took 6-8 hours PER PIECE. The Magazine took 8 hours, the skull on the barrel took 6, most parts took between 2-4
