On DeviantArt, desubunny has made several patterns for 3-D paper vocaloid dolls! They’re free, and anyone can make them. The only tools required are scissors, a printer and glue or tape. She has made multiple paper Vocaloid patterns and she’s even put up the links to some other users who have also put together some paper dolls… I mean paper action figures. She’s also constucted quite a few anime patterns. She’s made some from Devil Survivor, Reborn!, Black Rock Shooter, Hetalia, Rozen Maiden, D-Gray Man and a couple from the video game series, Touhou.
Here’s the link. Also, be sure to not buy this product. There’s an art thief stealing and selling the patterns! So, remember it’s free!
