3D Printed Medieval Barbie Armor

Zheng3’s Kickstarter project is to design 3D printable medieval armor for Barbie dolls. I see this as being a great transition to help girls ease their doll play from “let’s go shopping” to a much more active and kick-ass “let’s fight that nasty dragon and save the village.”
