Air Dancers are flying butterflys printed in one go that are powered by elastic bands. They come in multiple colours and patterns and there are also plain ones that can be drawn on. This model is one of the patterned models
Once printed you need to add a 50mm elastic band (doubled over) to the hooks and wind 30 times. You can then release the butterfly from your hands or from within a card or other object. See the attached documentation for some details
if you're interested in further patterns and models (including the plain one). they are availble on my patreon. https://patreon.com/catalyst3d
