Reduce outer diameter axis

[fred_dot_u]

Give this a look. I was able to construct a hollow cylinder with the inside diameter to match your desired dimension, with an outside diameter only a millimeter or two. Importing your file and the cylinder into Fusion 360, I was able to use the combine/cut feature to trim away the segment as you've indicated.

Meshmixer tells me the threaded features of the part are problematic, as does Fusion 360. Windows 10 3DBuilder ignores them, and I expect that the slicer you select will also ignore them.

Let me know if this meets your requirements or if it needs adjustment.
