Majora's mask from Majora's Mask.
Tried to be as true to the original artwork as possible.

Update: Scaled mask to wearable size. Should be close to "lifesized". Added Left and Right Halves with separate horns. Halves are sized and designed to fit on a makerbot replicator 2. Halves should print without support. Horns will need supports. Two alternatives exists one with open tear ducts so the wearer can see and the other with solid tearducts for hanging on a wall.

Print halves of model and horns and then glue together. Horn placement is identified with an scewed cone than ensures it can't go in the wrong place.

If printing on a makerbot replicator 2 it should fit perfectly in the build volume. If Makerware says "Object too large" click "Don't Scale". Apparently it's a bug in Makerware.
