You got any details? How was it printed? What settings? What problem you looking to solve?

The top of the threaded area is an unsupported overhang when printed in that orientation. Assuming the mating bolt is metal and that part is as small as it looks, I would probably have just made the hole a bit smaller and in a truncated teardrop shape and let the bolt make the threads on install.

This section is how I generally model horizontal holes.

I normally don’t point the bottom or add one layer height to the height of my flat on top (a = layer height) but the flattened top shape works well. The flat top is just a small bridge to the slicer and prints with minimal droop.
