I printed this face-up, letting Cura generate supports underneath. I used an 8mm brim around the part.
Sand it down a little, then spray it with Rust-Oleum gray auto primer.
Sand again to smooth it out, then spray with a Krylon hammered-metal paint.
Finally, add some detail by using brass-colored model car paint on the screw heads.
