Thread adapter for watering hose

I need this adapter to screw my watering hose to the tap. I drew it to fit the exact threads I have here. I also drew a washer for the female side, but the washer I printed in TPU gave inconsistent results, from tight seal to huge leaks.

I think they call these threads "¾" and "½" here, but I don't know why, since the actual dimensions are closer to 1 inch and ¾ of an inch, and we do not use inches here. Maybe that's why…

In order to avoid supports and get a strong piece, I printed the adapter in the orientation shown in the slicer screenshot. I added a brim just in case, it came off cleanly as soon as I pulled on it.

Happy printing!
