I took a bit more time and changed my setup so that the whole micrometer is in the image.
I hung the tool and lego brick with string and retouched the string out of the image. I used a two light setup with a 7" reflector and 10° grid to control the light spill as my key light and added a bit of fill from a light with a snoot.
I ended up not stacking as the shot seems to be sharp enough when shot with my 105mm lens at f/13. I tried focus stacking with Photoshop CC 2019, but found that the depth of field used and the distance from the subject at that aperture ended up being superior to the stacked image. I suspect the tiny bit of movement from the setup swaying caused issues in spite of using the align feature in Photoshop.
The micrometer is my daughter's that she bought for school. It was an inexpensive student model where the dust cover broke after 5 years of use. The high end Japanese replacement she just bought is about 3x more expensive.
I've ordered some Epson and Moab metallic papers and am looking to print this on these.
