The file 'LED Balloon Insert 3D Printer Model' is (stl) file type, size is 174.6KB.
An insert to put a DIP type LED inside a balloon and allow it to be filled and tied off easily.
Has recess in the bottom for a 2X10MM magnet.
This works with the throwie kit that we sell at LilyLEDs

The grooves are for tie-off's or elastics.
It will need a plug for inside the bottom or could put some thin tape or something over the magnet before inserting it to give a good seal.
Could also be used as a thrust or propellant device for balloon powered vehicles.
I printed one on a Makerbot and it needs to be upscaled maybe 3-4% for the pieces to fit in.
It did print better horizontally,
