Packing peanut. Air filled models to fill voids in boxes.

Sorry, this was meant to be a joke item. I don't know if this will even print or how effective it is to save your actual items from UPS. Or if this thing is even cost effective to waste as box filler.

I was just experimenting with OpenSCAD with rotate_extrude() and this was the silly design that came out of it.

Uploaded a bigger version, the one I tried printing came out smaller than I thought...
