Everything (except the backing) was sanded, primed with black primer, the center gear was then painted with Krylon Antique Brass spray paint and the three small gears were painted with a few coats each with Krylon metallic paint pens. All the gears were then sealed with a Krylon matte finish clear coat (no, I don't work for Krylon, it is just what they had when I want paint shopping).

I had picked up some XTC-3D filler, but I did not have the time to use it before I needed these for the party.

The backing fit perfectly under the lapel of the frock coat I had rented, I used some of the extra gears I had printed in silver filament to make some last minute cufflinks (not pictured).

The lapel gears worked great all not, I only bumped one off all night and noticed right away that I did. They turned perfectly against the fabric of the coat and they were a big hit. I am really happy with how this turned out and I give big Thanks to the projects that inspired me and the designer of the gears!
