This threaded adapter converts from 3/4" garden hose female to 15/16" faucet male. Make sure to use a washer on the garden hose side.
There are two version of the .stl file, one with a built-in supporting ring (break it off after printing), and another without any added supports. The supporting ring is calibrated for a 0.15mm layer height.
A special shout-out to Kipnugget who designed a female faucet to male G3/4 adapter. I messaged him about the reverse configuration, but by the time he replied I had already designed mine. Turns out he built one anyways, so check his out too: Threaded converter G3/4" - M22.
I used the tsmthread4 library to build this in OpenSCAD.
