PLA Packing Peanuts

More of a test and showcase of an idea than any fancy new design; it doesn't get much simpler than this.
Please go ahead and make larger sizes too. :)

Until sensible packaging that's biodegradable or easy to recycle becomes more widespread, in a pinch you can fill out any gaps around packages you have for postage with these little cylinders.
On output, they seem to be reasonably stiff, easily springing 1mm or so in diameter with a strong squeeze, and breakable at a few millimetres. They could be used to replace expanded polystyrene 'packing peanuts', whereever scrunched-up paper is too squishy.
It might be a good idea to cut a small amount of the material out of the model to reduce stiffness even more.

This gives the part thr
