Revised: I removed all of the options for the dials and provided one raised and one embossed design based on testing these work the best.

This thing is a micrometer dial for an for the Atlas lathe carriage stop by Lyle Peterson as shown at https://youtu.be/Weki8X5q5Mk

There are also drawings of the rest of the parts which must be made out of metal for strength available here: https://goo.gl/9dmklz

Dials print with threads and graduations which are the more time consuming/difficult parts of the build. Multiple graduation types are include. The version pictured is the embossed file. (STL files are in mm)

I rubbed white silicone caulk into the embossed lettering for visibility. I used caulk because it is thick enough to stay out from between the layers but fills in the embossing with high contrast and is chemically resistant.
