This is based from the Black Widow Perk in Fallout 4 and inspired by Porda's Sniper Pin.
Printed in Black with supports.
Ended up actually milling on the Othermill (which is why I've included an .svg file) for a cleaner and flatter part.
Fill areas with acrylic paint
make sure to let set over night. don't worry if it's a little messy, you'll clean it up later. Wait a full 8 hours to let the water evaporate from the paint
sand down to reveal clean borders and clean off excess paint
do a light sanding with 220 grit sandpaper
spray a clear coat or fixativ to seal the paints
paint a generous layer of clear nailpolish to finish
