This unicorn horn can be easily attached to a thin headband to wear as a costume for any unicorny purpose. It is not sized for a MakerBot but if you print it at 90% on a Replicator Plus you will get a delightful addition to your horse play. There is a hollowed area to insert an LED and battery if you so choose. The PLA I printed it out in was ice blue and the light, while not very clear in the picture, is stunning in the dark. Add floppy rainbow ears to delight any discerning Unicorn!
