These are a perfect costume fix: alien, robot, or insect. If you and your friends have a group costume thing going on, you can make as many of these as you need.

Like the Cat Ears, Mercreature Fins, and Horns in the Halloween 2012 series, these fit on a standard headband.

If you want to grab a pair right away, stop by the MakerBot Store!

Alien Antennae were created by Matt.
