This is a modified version of a nozzle for water ingress testing (DO-160 Part 10-2), specifically meant for printing in ABS (i.e. support free). Kudos goes to BishopsToenail for making the original; I just added a little support to the face. The support will snap off when removed from the build plate or can be snipped off.
I cannot guarantee that this fully conforms for any standard--the end user will need to check nozzle hole sizes and possibly bore them to the appropriate diameter.
Note: Decent quality results require small layer heights due to the steep angle of the nozzle. I've had great success at 0.12mm.
