I've printed several of these now, and they are very well done. I would make a few recomendations/changes depending on your usage though. IF you have headphones with the long microphone "pill" (for lack of a better description) in line with your cables it can be difficult to properly fit everything into the unit to close properly. Also if your ear phone connector is a straight connection (not a 90 degree) I have trouble fitting it into the area with the ear buds. Next time I print I will try to do about 5% larger and see if that fixes all my problems. Even if you have the big mic AND the straight jack, you can make it work, but it takes some fiddling with it to get it right. I do love the design, I think it is very well done. Kudos to the maker.
This printed up with no real tinkering or modification from me. I put everything on the same platform and printed at once. I think (I did this a while back) it took about ~1.5 hr to print? Don't quote me on it though, it was a week or so ago.
