SummaryI saw some neat rubber band powered surprise butterflies that fly outwhen people open cards, books, or packages. I wanted to make some thatare 3d printable.

Required:

LighterRubber bandSuper glue

To build:

Use super glue to attach the hub to the fuselage and let dry.CAREFULLY use a lighter to soften the wing arms on the rotor andtwist them slightly so it becomes like a propeller. I find that a twist ofabout 45 degrees works well.Install the rotor into the hub and attach the rubber band on thehooks.

You may need to clean up the hub and the rotor so that the rotor spinsfreely. I found that just spinning the rotor inside the hub for a while wearsit in and then it works better.

The wings should be one layer or about 0.2mm thick. If the wings arethicker, the toy might be too heavy to fly. Different slicers seem to havetrouble with single layer thick parts so it might take some tinkering to getright. I've included several different model options you can try to seewhich one plays nice with your slicer (one with 0.4mm thick wings, onewith 0.2mm thick wings, and one with 0.12mm thick wings). Make sureyour bed is level!
