My eldest son wanted to trick or treat as Skull Kid. I had no idea what that was. He showed me a picture of Majora's Mask, and then showed me how much they cost on etsy. Yikes! So, I decided to build it. The actual cost for the entire costume was pretty cheap... fabric and wooden curtain hangers from GoodWill (belt), A few bucks of Acrylic paint, a bottle of elmers glue, and a heart shaped balloon. All in, less than 15 bucks. Anyway... Turns out that Majora's Mask is actually the shape of a big heart. I paper Mache'd the mask (about 6 layers), and used a glue gun to to outline the lines and mask regions. That made it much easier to finish painting once I'd primed with white. Turns out that glue guns work really well on both paper mache AND PLA. So, it was really easy to attach the eyes and horns to the mask. My 14 year old son and his friends described the finished product as awesome. So, I'm thinking I did OK. BTW... You can use acrylic paint right on top of the PLA. You can use pretty light infill for the eyes... 10 - 15%. The horns are printed as spiral vase. And the belt buckle is really just a two sided snap that connects the curtain rings in any desired length. I printed them double wall with 15% infill, knowing they only needed to last one night, and gave my son a couple of extras in case of breakage during trick or treating. You'll need to scale up or down both the eyes and horns based on the size of your mask.
