It is made of 3 simple stl files, designed on Rhino3d (the cuff is heavily borrowed from the beehive bracelet here on thingiverse), the upright body, the wings, and the cuff. After cleaning off the rafts and getting rid of excess plastic in the slit at the rear where the battery slides in (I used either a dremel or a pair of small scissors - it is a snug but not precise fit), wings are glued onto the back with hot melt glue, the bracelet to the belly, and simply clip the leads of any 3V flashing LED to about 4 mm, press it over the +/- faces of a 2032 coin battery and insert it into the posterior abdomen and you are ready to wear.
