Use caution and at your own risk when pressurizing! Use proper fittings in high pressure situations!
I spliced the NPT threads from dcreel's and nebarnix's models to make this fitting.
There are 2 versions the only difference is the 1/8" NPT end on V2 is about 3mm shorter.
I printed version 2 (pictured) at 100% fill density for my airbrush hose coupling.
