If you're like me, then you likely have a set of keys that you ocasionally pull out of your key chain... So, to make your life a little easier, just unscrew it from the lot.
Print at 0.20-0.25mm layer height, 25% infill and you're good to go.
Add some supports on the inside of the female part.
Hope you enjoy this ;)
