I have an Etsy shop for simple custom Funko figures, and I've gotten orders for a few different custom Shepards to match the buyers' in-game characters. The black-haired ones ended up being a little more complicated because Mikasa have heads made differently from the others, all one piece of much thicker plastic instead of lighter plastic with a separate neck ring, so I ended up having to use my rotary tool to shave down the neck peg or widen the neck hole.
