Reproduction of rank epaulettes from The Orville (Commander, Lt. Commander, Lieutenant, and Ensign).
Because of the tiny details making up the diagonal stripes on the main surface of the top face, it's pretty much impossible to sand that area without destroying them.
0.4mm nozzle, 0.12mm layers
I printed it diagonally, with the wide end higher than the narrow end, in an attempt to reduce plateau artifacts on the shallow curve of the top face.
After printing, I gave it a couple of coats of high-build primer, then sanded it smooth (everywhere except the problematic large area on the top face) using a variety of increasing grits.
Then I masked off the various differently colored areas with yellow Frog tape and airbrushed them.
Finally, I epoxied a strip of Velcro (hook side) onto the back, for affixing it to the uniform.
Modeled in Blender, based on numerous screenshots of various characters.
Unfortunately, I couldn't find a camera angle (or a high-res promo photo) that allowed me to clearly see the text on the medium-grey area of the top face, so I used some of the text from Captain Mercer's epaulettes instead.
